μ(2)-Iodido-bis-{dimeth-yl[methyl-bis(quinolin-8-yl)silanyl-κN,Si,N']platinum(IV)} tetra-kis(penta-fluoro-phen-yl)borate dichloro-methane 0.66-solvate.

The title complex, [Pt(2)(CH(3))(4)(C(19)H(15)N(2)Si)(2)I][B(C(6)F(5))(4)]·0.66CH(2)Cl(2), resulted from an attempt to synthesize a stable five-coordinate platinum species via ligand abstraction of a six-coordinate platinum precursor. However, dimerization occurred after ligand abstraction, thereby yielding the compound described in this study. The cation is a dinuclear Pt(IV) organometallic complex, in which the metal centers are bridged by an I(-) anion. Both metal centers display a coordination geometry close to octa-hedral, including cis-arranged quinoline ligands connected by Si atoms, which form Pt-Si bonds, two cis-methyl groups, and the bridging I(-) anion. In the crystal structure, voids between cations and anions are partially filled with an average of 0.66†mol-ecules of dichloro-methane solvent.
