(μ-trans-1,2-Di-4-pyridylethyl­ene-κ(2) N:N′)bis­[bis­(N,N-diethyl­dithio­carbamato-κ(2) S,S′)zinc(II)] chloro­form solvate

The dinuclear title solvate, [Zn(2)(C(5)H(10)NS(2))(4)(C(12)H(10)N(2))]·CHCl(3), features two five-coordinate Zn atoms; both coordination polyhedra are distorted, but one has an NS(4) donor set approximating to a square pyramid (with the N atom in the apical site), while the other is closer to a ZnNS(4) trigonal-bipyramidal arrangement (with the N atom in an equatorial site). In both cases, the Zn(II) atom is chelated by two S,S′-bidentate dithiol­ate ligands. In the crystal, the chloro­form solvent mol­ecules reside in cavities defined by the dinuclear species and are held in place via C—H⋯S contacts.
