μ-4,4′-Bipyridyl-1:2κ(2) N:N′-methanol-2κO-tetrakis(tri-tert-butoxy­silanethiol­ato)-1κ(4) O,S;2κ(2) S-dizinc(II)

The title compound, [Zn(2)(C(12)H(27)O(3)SSi)(4)(C(10)H(8)N(2))(CH(4)O)], 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.
