A dimeric heteroleptic five-coordinate zinc(II) complex containing a non-motionally restricted N,N′-heterocyclic ligand

Abstract

The title compound, bis(μ-1,2-benzenethiolato)-1:2κ3 S,S′:S′;2:1κ3 S,S′:S′-bis[(2,2′-bipyridine-κ2 N,N′)zinc(II)], [Zn2(μ-C6H4S2)2(C10H8N2)2], crystallizes with the dinuclear molecule located on a center of symmetry. The coordination geometry about the Zn atom is a modestly distorted trigonal bipyramid, with the axial ligating atoms at an angle of 170.81 (4)° and the angles in the equatorial plane in the range 112.94 (4)–129.95 (4)°. Weak π-stacking interactions between bipyridine ligands on adjacent molecules [interplanar spacing = 3.315 (3) Å] and a possible weak intermolecular C—H...S hydrogen bond (H...S = 2.84 Å) are seen in the crystal.
