Abstract: 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 Pt^IV 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.
