μ2-Iodido-bis­{dimeth­yl[methyl­bis(quinolin-8-yl)silanyl-κ3 N,Si,N′]platinum(IV)} tetra­kis(penta­fluoro­phen­yl)borate dichloro­methane 0.66-solvate

摘要

The title complex, [Pt2(CH3)4(C19H15N2Si)2I][B(C6F5)4]·0.66CH2Cl2, 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 PtIV organometallic complex, in which the metal centers are bridged by an I− anion. Both metal centers display a coordination geometry close to octa­hedral, 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 mol­ecules of dichloro­methane solvent.
