Abstract
Platinum(II) complexes bearing acetylide ligands containing nucleobase motifs are prepared and their impact on human topoisomerase II (TopoII) is evaluated. Both platinum(II) complexes [Pt(II)(C^N^N)(C≡CCH₂R)] (1a-c) and [Pt(II)(tBu₃terpy)(C≡CCH₂R)](+) (2a-c) (C^N^N=6-phenyl-2,2'-bipyridyl, tBu₃terpy=4,4',4''-tri-tert-butyl-2,2':6',2''-terpyridyl, and R=(a) adenine, (b) thymine, and (c) 2-amino-6-chloropurine) are stable in aqueous solutions for 48 hours at room temperature. The binding constants (K) for the platinum(II) complexes towards calf thymus DNA are in the order of 10⁵ dm³ mol⁻¹ as estimated by using UV/Vis absorption spectroscopy. Of the complexes examined, only complexes 1a-c are found to behave as intercalators. Both complexes 1a-c and 2a-c inhibit TopoII-induced relaxation of supercoiled DNA, while 2c is the most potent TopoII inhibitors among the tested compounds. Inhibition of DNA relaxation is detected at nanomolar concentrations of 2c. All of the platinum(II) complexes are cytotoxic to human cancer cells with IC₅₀ values of 0.5-13.7 μM, while they are less toxic against normal cells CCD-19 Lu.

Abstract
Luminescent cyclometalated platinum(II) complexes, namely [Pt(Thpy)(PPh3)X]n+ (HThpy = 2-(2′-thienyl)pyridine; X = Cl− (1), n = 0; X = CH3CN (2), pyridine (3), n = 1) and [Pt(Thpy)(HThpy)Y]n+ (Y = Cl− (4), n = 0; Y = pyridine (5), n = 1), exhibit structured emission with peak maximum at ∼556 and 598 nm in degassed acetonitrile and with emission quantum yield and lifetime of up to 0.38 and 26 μs, respectively. These complexes are efficient photosensitizers of singlet oxygen with yields up to >90%. Complex 5 exhibited photocytotoxicity towards cancer cells and fluorescence microscopic images of cells incubated with 5 reveal substantial uptake at the nucleus and mitochondria.

Abstract
A trinuclear cyclometalated Pt(II) 4,6-diphenyl-2,2'-bipyridyl complex with bis(diphenylphosphinomethyl)phenylphosphine bridging ligand ([4-Ph(C--N--N)Pt](3)dpmp) has been synthesized and characterized. It exhibits a broad electronic absorption band from 400 to 600 nm because of its intramolecular Pt...Pt interactions that have been revealed by X-ray crystal structure analysis. This complex shows strong red emission in acetonitrile at room temperature and 77 K. The electronic and emission spectra exhibit concentration and temperature dependence. With increased concentrations, the UV band of the absorption spectrum gradually decreases and broadens, accompanied by an increase of the (1)[dsigma*,pi*] band between 400 and 600 nm. For emission spectra, the 550 nm band that originates from the mononuclear platinum(II) component gradually decreases with increased concentrations, while the band at approximately 700 nm that corresponds to the (3)[dsigma*,pi*] state increases. In addition, the UV-vis and emission spectra exhibit temperature and viscosity-dependence. The concentration-, temperature-, and viscosity-dependent characteristics indicate a conformational change of the complex arising from the rotation along the oligophosphine axis. This complex exhibits broad, positive, and strong transient difference absorption bands from the near-UV to near-IR spectral region. However, because of the increased ground-state absorption in the visible region, the nonlinear transmission of this trinuclear platinum complex decreases.

Abstract
The (benzophenone imine)platinum(II) compounds trans-[PtCl2(Ph2C=NH)(RR'SO)] [R, R'=Me, Me (2); n-Pr, n-Pr (3); (CH2)4 (4); Me, Ph (5); Me, p-MeC6H4 (6)] were prepared by the reaction of Ph2C=NH with K[PtCl3(RR'SO)], obtained in situ from K2[PtCl4] and the corresponding sulfoxide, giving 2-6 as well as cis-[PtCl2(Ph2C=NH)2] (1) as a minor product. The complexes were characterized by 1H, 13C, and 195Pt NMR and IR spectroscopy, electrospray ionization mass spectrometry, and C, H, and N elemental analysis. The X-ray crystallography of 1 enables confirmation of the cis configuration of the complex, while in 2 and 4.1/2CHCl3, the imine and sulfoxide ligands are mutually trans. The solid-state structure of 4.1/2CHCl3 consists of two dimeric Pt moieties representing a rather weak Pt...Pt interaction. The dimeric architecture of 4.1/2CHCl3 is enhanced by the hydrogen bonding between imine H atoms and O atoms. The orthometalation of 1 and 2-6 proceeds both in the solid phase and in a toluene suspension, leading to the formation of [PtCl{Ph(C6H4)C=NH}(Ph2C=NH)] (7) and [PtCl{Ph(C6H4)C=NH}(RR'SO)] (8-12), respectively, isolated in nearly quantitative yields. Complexes 8-12 are emissive at room temperature both in solution (lambdaemmax approximately 535 nm) and in the solid state (lambdaemmax 560-610 nm), with excited-state lifetimes of ca. 300-600 ns, representing a new family of PtII-based luminescent complexes. Compounds 8 and 10 have been characterized by X-ray analysis, confirming the square-planar coordination geometry of the metal center with the almost planar platinacycles. In 8, the asymmetric unit contains two independent Pt molecules, while in 10, it includes four Pt molecules linked by the intermolecular hydrogen-bonding network between the NH group and Cl atoms.

Abstract
Preparation of a triisocyanide ligand, 1,3,5-tris[(4-isocyano-3,5-diisoproyl-phenyl)ethynyl]benzene (5), is presented. Ligand 5 is obtained in three steps in 76% overall yield. Reaction of 5 with (eta5-Cp*)Rh(Cabs,s')(Cabs,s'= 1,2-S2C2B10H10-S,S') produced the rhodadithiolene adduct [[(eta5-Cp*)Rh(Cabs,s')(CNC6H2iPr2-2,6-CC-3)]3C6H3-1,3,5] (6). Ligand 5 reacts with Cr(CO)5(THF) to give the triisocyanide complex [[Cr(CO)5(CNC6H2iPr2-2,6-CC-3)]3C6H3-1,3,5] (8) and with [AuCl(SMe2)] to give the triisocyanide complex [[AuCl(CNC6H2iPr2-2,6-CC-3)]3C6H3-1,3,5] (9). As revealed by a single-crystal X-ray diffraction study, the C(9)-N(3)-C(61) angle of 5.9 degrees of trichromium complex 8 occurs in the plane of the bridge and the gold center has a slightly bent linear configuration with a Cl(1)-Au(1)-C(21) angle of 175.4(4) degrees . The rhenation and platination of 5 employing [Re(bpy)(CO)3(AN)]PF6 (AN= acetonitrile) and [(CwedgeNwedgeN)PtCl] ((HCwedgeNwedgeN)= 6-phenyl-2,2'-bipyridine) yielded the luminescent Re(I) and Pt(II) complexes. Full characterization includes structural study of complexes 2, 8, and 9.

Abstract
Starting from tris(benzothiazol-2-yl)phosphane (1) an advanced Janus-head ligand, di(benzothiazol-2-yl)phosphane (2), was synthesised and structurally characterised. The heteroaryl substituents of this ligand provide both hard and soft donor sites. Surprisingly, the phosphorus atom in 2 is divalent and the hydrogen atom is directly bonded to one ring nitrogen atom and hydrogen bonded to the second. Compound 2 decomposes in any common solvent other than diethyl ether and a new preparation to improve the yields of 2 is presented. A coordination polymer, [{Cs(bth)(2)P}8] (3) (bth=benzothiazol-2-yl), was obtained when the sec-phosphane 2 was allowed to react with elemental caesium in a 1:1 ratio in diethyl ether at -78 degrees C. In 3 each anion is coordinated to four caesium cations and vice versa. The central phosphorus atom is coordinated to two metal atoms above and below the mean plane of the anion in positions in which the two lone pairs of a four-electron donor are anticipated. Two additional cations micro-bridge both ring nitrogen atoms. Hence both faces of the Janus-head ligand are coordinated to the same number of metal cations but in a different way.

Abstract
The crystal structures and photophysical properties of mononuclear [(RC N N)PtX](ClO4)n ((RC N N)=3-(6'-(2''-naphthyl)-2'-pyridyl)isoquinolinyl and derivatives; X=Cl, n=0; X=PPh(3) or PCy(3), n=1), dinuclear [(RC N N)2Pt2(mu-dppm)](ClO4)2 (dppm=bis(diphenyphosphino)methyl) and trinuclear [(RC N N)3Pt3(mu-dpmp)](ClO4)3 (dpmp=bis(diphenylphosphinomethyl)phenylphosphine) complexes are presented. The crystal structures show extensive intra- and/or intermolecular pipi interactions; the two (RC N N) planes of [(RC N N)2Pt2(mu-dppm)](ClO4)2 (R=Ph, 3,5-tBu2Ph or 3,5-(CF3)2Ph) are in a nearly eclipsed configuration with torsion angles close to 0 degrees. [(RC N N)PtCl], [(RC N N)2Pt2(mu-dppm)](ClO4)2, and [(RC N N)3Pt3(mu-dpmp)](ClO4)3 are strongly emissive with quantum yields of up to 0.68 in CH2Cl2 or MeCN solution at room temperature. The [(RC N N)PtCl] complexes have a high thermal stability (T(d)=470-549 degrees C). High-performance light-emitting devices containing [(RC N N)PtCl] (R=H or 3,5-tBu2Ph) as a light-emitting material have been fabricated; they have a maximum luminance of 63,000 cd m(-2) and CIE 1931 coordinates at x=0.36, y=0.54.
