Abstract: The title compound, [Zn₂(C₁₂H₂₇O₃SSi)₄(C₁₀H₈N₂)(CH₄O)], is a binuclear complex with the two Zn^II atoms linked via a bridging 4,4'-bipyridyl ligand. One of the Zn^II atoms is penta-coordinated by two O,S-chelating tri-tert-butoxysilanethiolate units and one N atom of a 4,4'-bipyridine ligand, and the other Zn^II atom is tetrahedrally coordinated by two tri-tert-butoxysilanethiolate anions acting as monodentate S ligands, the methanol O atom and the other N atom of the 4,4'-bipyridine ligand. This non-symmetrical coordination induces twisting and bending in the 4,4'-bipyridine ligand and introduces chirality into the system. The crystal studied exhibits inversion twinning. One tert-butyl group is disordered approximately equally over two positions.
