Abstract
The structure of the title compound, [Ca(C(10)H(15)O(4)S)(2)(H(2)O)(4)], is the first example in which two D-camphor-10-sulfonate anions are coordinated to a metal ion, in this case with direct Ca-O bonding. The molecule has crystallographically imposed twofold symmetry with the Ca atom on the twofold axis. Hydrogen bonds are formed between the coordinated water molecules and the O atoms of the SO(3)(-) groups of adjacent molecules, leading to the formation of a two-dimensional layered network. The compound displays sharp wavelength-selective transparency in the UV-visible spectrum, offering the potential for application as an optical filter.

Abstract
In the crystal structure of the title compound, C(12)H(26)N(2)O(4) (2+)·2(Br(0.085)Cl(0.915))(-)·4C(5)H(9)OH, the complete cation is generated by crystallographic twofold symmetry. Contamination of the chloride counter-anion with bromide occured during the preparation, due to the use of 1,2-dibromo-ethane. One of the solvent mol-ecules is disordered, with occupancies 0.53 (3):0.47 (3). The crystal packing is stabilized by an infinite two dimensional ⋯X⋯H-N-H⋯X⋯ hydrogen-bonding network (X: Br(-)/Cl(-) ≃ 1:12). In addition, O-H⋯X and O-H⋯O hydrogen bonds involving solvent mol-ecules are observed.

Abstract
[Na(2)(thf)(4)(P(4)Mes(4))] () (Mes = 2,4,6-Me(3)C(6)H(2)) reacts with one equivalent of [PtCl(2)(cod)] (cod = 1,5-cycloctadiene) or [PtCl(2)(dppe)] (dppe = bis(diphenylphosphino)ethane) to give the corresponding platinum(II) tetramesityltetraphosphane-1,4-diide complexes [Pt(P(4)Mes(4))(cod)] () and [Pt(P(4)Mes(4))(dppe)] (). The Pt-P bonds of these complexes proved to be extraordinarily stable and did not react with insertion reagents such as tert-butyl isocyanide or cyclohexyl isocyanide. Instead, ligand transfer occurred to give [Pt(P(4)Mes(4))(C[triple bond, length as m-dash]NBu(t))(2)] () and [Pt(P(4)Mes(4))(C[triple bond, length as m-dash]NCy)(2)] (). Further reactions of with CO, CS(2), white phosphorus, MeI and ethyl diazoacetate led either to formation of cyclo-P(4)Mes(4) and cyclo-P(3)Mes(3) or to unidentified products, in which no evidence of insertion of these reagents into the Pt-P bond was observed.

Abstract
In the title complex, [Rh(C6H16P2)2][RhCl2(C8H12)], the asymmetric unit contains two [Rh(dmpe)2] [dmpe = 1,2-bis(dimethylphosphino)ethane] half-cations, lying on inversion centers, and an [RhCl2(cod)]− (cod = 1,5-cyclooctadiene) anion, wherein Rh is coordinated by two chloride ligands and two olefinic π-bonds of the cyclooctadiene ligand. The Rh atoms in the cations and anion exhibit square-planar coordination and are separated without any unusual interactions.

Abstract
The reaction of 3-methoxyphenylacetic acid (3-MPAH), 4-methoxyphenylacetic acid (4-MPAH), 2,5-dimethyl-3-furoic acid (DMFUH) or 1,4-benzodioxane-6-carboxylic acid (BZDOH) with triphenyltin(IV) chloride (1:1) or diphenyltin(IV) dichloride (2:1) in the presence of triethylamine yielded the compounds [SnPh3(3-MPA)] (1), [SnPh3(4-MPA)] (2), [SnPh3(DMFU)] (3), [SnPh3(BZDO)] (4), [SnPh2(3-MPA)2] (5), [SnPh2(4-MPA)2] (6), [SnPh2(DMFU)2] (7) and [SnPh2(BZDO)2] (8), respectively. The tetranuclear complex [{Me2(DMFU)SnOSn(DMFU)Me2}2] (9) was prepared by the reaction of dimethyltin(IV) oxide and 2,5-dimethyl-3-furoic acid (DMFUH). The molecular structures of 3, 4 and 9, were determined by X-ray diffraction studies. The cytotoxic activity of the carboxylic acids (3-MPAH, 4-MPAH, BZDOH and DMFUH) and di (5-8) and triphenyltin(IV) complexes (2-4) was tested against tumor cell lines human adenocarcinoma HeLa, human myelogenous leukemia K562, human malignant melanoma Fem-x and normal immunocompetent cells, peripheral blood mononuclear cells PBMC. Triphenyltin(IV) complexes show higher activities than the diphenyltin(IV) derivatives. The most active compound is [SnPh3(DMFU)] (3) with IC50 value of 0.15+/-0.01, 0.051+/-0.004, 0.074+/-0.004, 0.20+/-0.01, 0.15+/-0.02 on HeLa, K562, Fem-x, rested and stimulated PBMC, respectively, while the most selective are [SnPh2(3-MPA)2] (5), [SnPh(2)(DMFU)2] (7) and [SnPh((BZDO)2] (8). Compounds 3, 5, 7 and 8 present higher activities than cisplatin in all the tested cells and relative high selectivity especially on K562 cells.

Abstract
The structure of the title complex, [Mg(H2O)6](C10H15O4S)2, consists of regular octahedral [Mg(H2O)6]2+ cations and d-camphor-10-sulfonate anions. A three-dimensional supramolecular architecture is formed via hydrogen-bond interactions [O—H⋯O = 2.723 (2)–2.833 (2) Å] to give alternating layers of [Mg(H2O)6]2+ cations and d-camphor-10-sulfonate anions. The title compound is isomorphous with the zinc, copper, cadmium and nickel analogues.

Abstract
[K(2)(P(4)Mes(4))] (1) or [Na(2)(THF)(4)(P(4)Mes(4))] (2) (Mes = 2,4,6-Me(3)C(6)H(2)) reacts with one equivalent of HCl and subsequently with 0.5 equivalents of [{RhCl(cod)}(2)] (cod = 1,5-cyclooctadiene) to give a mixture of rhodium complexes, from which [Rh(P(4)HMes(4))(cod)] (3) and the secondary product [Rh(2)(micro-P(2)HMes(2))(mu-PHMes)(cod)(2)] (4) were isolated and characterised by X-ray diffraction studies. Alternatively, the reaction of [K(2)(P(4)Ph(4))] (5) or [Na(2)(THF)(5)(P(4)Ph(4))] (6) with one equivalent of HCl and subsequently with one equivalent of [CuCl(PCyp(3))(2)] (Cyp = cyclo-C(5)H(9)) gave the complex [Cu(4)(P(4)Ph(4))(2)(PH(2)Ph)(2)(PCyp(3))(2)] (7), presumably via disproportionation of the monoanion (P(4)HPh(4))(-).

Abstract
Two new p-cymene ruthenium(II) complexes containing as additional ligands N-methylpiperazine ([(?6-p-cymene)RuCl2(CH3NH(CH2)4NH)]PF6, complex 1) or vitamin K3-thiosemicarbazone ([(?6-p-cymene)RuCl2(K3tsc)], complex 2) were synthesized starting from [(?6-p-cymene)2RuCl2]2 and the corresponding ligand. The complexes were characterized by elemental analysis, IR, electronic absorption and NMR spectroscopy. The X-ray crystal structure determination of complex 1 revealed ?piano-stool? geometry. The differences in the cytotoxic activity of the two complexes are discussed in terms of the ligand present.

Abstract
Na[cyclo-(P(5)tBu(4))] (1) reacts with [NiCl(2)(PEt(3))(2)] and [PdCl(2)(PMe(2)Ph)(2)] with elimination of tBuCl and formation of the corresponding metal(0) cyclopentaphosphene complexes [Ni{cyclo-(P(5)tBu(3))}(PEt(3))(2)] (2) and [Pd{cyclo-(P(5)tBu(3))}(PMe(2)Ph)(2)] (3). In contrast, complexes with the more labile triphenylphosphane ligand, such as [MCl(2)(PPh(3))(2)] (M=Ni, Pd), react with 1 with formation of [NiCl{cyclo-(P(5)tBu(4))}(PPh(3))] (4) and [Pd{cyclo-(P(5)tBu(4))}(2)] (5), respectively, in which the cyclo-(P(5)tBu(4)) ligand is intact. In the case of palladium, the cyclopentaphosphene complex [Pd{cyclo-(P(5)tBu(3))}(PPh(3))(2)] (6) in trace amounts is also formed. However, [Ni{cyclo-(P(5)tBu(4))}(2)] (7) is easily obtained by reaction of two equivalents of 1 and one equivalent of [NiCl(2)(bipy)] at room temperature. Complex 7 rearranges on heating in n-hexane or toluene to the previously unknown [Ni{cyclo-(P(5)tBu(4))PtBu}{cyclo-(P(4)tBu(3))}] (8), which presumably is formed via the intermediate [Ni{cyclo-(P(5)tBu(4))}{cyclo-(P(4)tBu(3))PtBu}], which, after an unexpected and unprecedented phosphanediide migration, gives 8, but always as an inseparable mixture with 7. In the reaction of 1 with [PtCl(2)(PPh(3))(2)], ring contraction and formation of [PtCl{cyclo-(P(4)tBu(3))PtBu}(PMe(2)Ph)] (9) is observed. Complexes 3-5 and 7-9 were characterised by (31)P NMR spectroscopy, and X-ray structures were obtained for 5-9.

Abstract
The bulky substituted cyclopentadienyllithium derivatives, LiC5H4(CHMeR) (R = C6H5 (1), 1-naphthyl (2), 9-anthryl (3)), were synthesized from the reaction of 6-phenylfulvene, 6-(1-naphthyl)fulvene or 6-(9-anthryl)fulvene with LiMe. The ansa-bis(cyclopentadiene) ligands Me2Si(C5HMe4){C5H4(CHMeR)} (R = C6H5 (4), 1-naphthyl (5), 9-anthryl (6)), and their lithium derivatives Li2(Me2Si(C5Me4){C5H3(CHMeR)}) (R = C6H5 (7), 1-naphthyl (8), 9-anthryl (9)) have been prepared. The zirconocene complexes, [Zr(η5-C5H5){η5-C5H4- (CHMeR)}Cl2] (R = C6H5 (10), 1-naphthyl (11), 9-anthryl (12)) and [Zr{η5-C5H4(CHMeR)}2Cl2] (R = C6H5 (13), 1-naphthyl (14), 9-anthryl (15)), were synthesized by the reaction of lithium derivatives 1-3 and [Zr(η5-C5H5)Cl3] or ZrCl4, respectively. The reaction of the lithium ansa-derivatives 7-9 and zirconium tetrachloride yielded the ansa-zirconocene complexes, [Zr(Me2Si(η5-C5Me4){η5-C5H3(CHMeR)})Cl2] (R = C6H5 (16), 1-naphthyl (17), 9-anthryl (18)). The zirconocene complexes have been tested in the polymerization of ethene and propene. The polymerization of propene with the ansa-zirconocene catalysts 16-18 gave polypropylene with 70% mmmm pentads and the symmetric zirconocene catalysts 13-15 30-60% mmmm pentads.
