C2-isomer of [Pd(tfd)] 6 [tfd is S 2C 2(CF 3) 2] as its benzene solvate: a new member of the small but growing class of homoleptic palladium(II) monodi-thio-lenes in the form of hexa-meric cubes.

Abstract
The title compound, hexa-kis-[μ3-1,2-bis-(tri-fluoro-meth-yl)ethene-1,2-di-thiol-ato]-octa-hedro-hexa-palladium(II), [Pd(C4F6S2)]6, crystallizes as its benzene solvate, [Pd(tfd)]6·2.5C6H6, where tfd is the di-thiol-ene S2C2(CF3)2. The mol-ecular structure of [Pd(tfd)]6 is of the hexa-metallic cube type seen previously in three examples of hexa-meric homoleptic palladium monodi-thiol-ene structures. All structures have in common: (a) the cluster closely approximates a cube containing six PdII atoms, one at the centre of each cube face; (b) 12 S atoms occupy the mid-points of all 12 cube edges, providing for each PdII atom an approximately square-planar S4 environment; (c) each S atom is part of a di-thiol-ene mol-ecule, where the size of the di-thiol-ene ligand necessitates that only sulfur atoms on adjacent cube edges can be part of the same di-thiol-ene. This general cube-type framework has so far given rise to two isomeric types: an S6-symmetric isomer and a C2-chiral type (two isomers that are enanti-omers of each other). The structure of [Pd(tfd)]6 is of the C2-type. Out of the 12 CF3 groups, three are rotationally disordered over two positions. Further, we answer the question of whether additional, previously undiscovered, isomers could follow from the cube rules (a) through (c) above. An exhaustive analysis shows that no additional isomers are possible and that the list of isomers (one S6 isomer, two C2 enanti-omers) is complete. Each isomer type could give rise to an unlimited number of compounds if the specific di-thiol-ene used is varied.

Abstract
In the title compound, (C(24)H(20)As)[Pt(C(4)F(6)S(2))(2)], the cation lies on a twofold rotation axis while the anion has crystallographic inversion symmetry. The Pt(II) ion is in a slightly distorted square-planar coordination environment. The F atoms of both unique -CF(3) groups are disordered over two sets of sites, the ratios of refined occupancies being 0.677 (15):0.323 (15) and 0.640 (16):0.360 (16). The crystal structure is the first to date of a monoanionic [Pt(tfd)(2)](-) species [tfd is 1,2-bis-(trifluoro-meth-yl)ethene-1,2-dithiol-ate] with a non-redox-active cation.

Abstract
Transition-metal dithiolene complexes have interesting structures and fascinating redox properties, making them promising candidates for a number of applications, including superconductors, photonic devices, chemical sensors, and catalysts. However, not enough is known about the molecular electronic origins of these properties. Multinuclear solid-state NMR spectroscopy and first-principles calculations are used to examine the molecular and electronic structures of the redox series [Pt(tfd)(2)](z-) (tfd = S(2)C(2)(CF(3))(2); z = 0, 1, 2; the anionic species have [NEt(4)](+) countercations). Single-crystal X-ray structures for the neutral (z = 0) and the fully reduced forms (z = 2) were obtained. The two species have very similar structures but differ slightly in their intraligand bond lengths. (19)F-(195)Pt CP/CPMG and (195)Pt magic-angle spinning (MAS) NMR experiments are used to probe the diamagnetic (z = 0, 2) species, revealing large platinum chemical shielding anisotropies (CSA) with distinct CS tensor properties, despite the very similar structural features of these species. Density functional theory (DFT) calculations are used to rationalize the large platinum CSAs and CS tensor orientations of the diamagnetic species using molecular orbital (MO) analysis, and are used to explain their distinct molecular electronic structures in the context of the NMR data. The paramagnetic species (z = 1) is examined using both EPR spectroscopy and (13)C and (19)F MAS NMR spectroscopy. Platinum g-tensor components were determined by using solid-state EPR experiments. The unpaired electron spin densities at (13)C and (19)F nuclei were measured by employing variable-temperature (13)C and (19)F NMR experiments. DFT and ab initio calculations are able to qualitatively reproduce the experimentally measured g-tensor components and spin densities. The combination of experimental and theoretical data confirm localization of unpaired electron density in the pi-system of the dithiolene rings.

Abstract
Nickel bis(dithiolene) complexes have been known for over four decades, yet little is known regarding the chemistry of this important subclass of inorganic coordination complexes in olefin oligomerization or polymerization. We report here that Ni(S(2)C(2)R(2))(2) (R=Ph, CF(3)) are converted to active catalysts for ethylene oligomerization when activated with methylaluminoxane (MAO). The catalyst activity is comparable to some nickel coordination complexes with N-donor ligands under similar conditions. The products are mainly butenes and hexenes, with small amounts of higher oligomers. The product distribution pattern is consistent with a nickel hydride species being the active center, where fast beta-hydride elimination limits the products to mostly butenes and hexenes. The exact nature of the active center and the reaction mechanism remain to be investigated. In addition, we determined the crystal structure for Ni[S(2)C(2)(CF(3))(2)](2). The molecule crystallizes in the P2(1)/n space group and adopts a planar geometry with expected bond lengths and angles. Comparing this structure with that for the donor-acceptor complex with perylene reveals elongation of both the Ni-S and the S-C bonds in the latter, suggesting reduction of Ni[S(2)C(2)(CF(3))(2)](2) may have occurred in the latter.
