[μ(2)-trans-1,2-Bis­(pyridin-4-yl)ethene-κ(2) N:N′]bis­{[1,2-bis­(pyridin-4-yl)ethene-κN]bis­[N-(2-hydroxy­eth­yl)-N-iso­propyl­dithio­carbamato-κ(2) S,S′]cadmium} aceto­nitrile tetra­solvate: crystal structure and Hirshfeld surface analysis

The asymmetric unit of the title compound, [Cd(2)(C(12)H(10)N(2))(3)(C(6)H(12)NOS(2))(4)]·4C(2)H(3)N, comprises a Cd(II) atom, two di­thio­carbamate (dtc) anions, one and a half trans-1,2-dipyridin-4-yl­ethyl­ene (bpe) mol­ecules and two aceto­nitrile solvent mol­ecules. The full binuclear complex is generated by the application of a centre of inversion. The dtc ligands are chelating, one bpe mol­ecule coordinates in a monodentate mode while the other is bidentate bridging. The resulting cis-N(2)S(4) coordination geometry is based on an octa­hedron. Supra­molecular layers, sustained by hy­droxy-O—H⋯O(hy­droxy) and hy­droxy-O—H⋯N(bpe) hydrogen bonding, inter­penetrate to form a three-dimensional architecture; voids in this arrangement are occupied by the aceto­nitrile solvent mol­ecules. Additional inter­molecular inter­actions falling within the specified framework have been analysed by Hirshfeld surface analysis, including π–π inter­actions.
