Abstract: The dinuclear title solvate, [Zn₂(C₅H₁₀NS₂)₄(C₁₂H₁₀N₂)]·CHCl₃, features two five-coordinate Zn atoms; both coordination polyhedra are distorted, but one has an NS₄ donor set approximating to a square pyramid (with the N atom in the apical site), while the other is closer to a ZnNS₄ 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-HS contacts.
