Bottom Line: In the title complex, [Cu(C16H24N3S2)2], the Cu(II) atom is coordinated by two azomethine N and two thiol-ate S atoms of the chelating Schiff base ligands, resulting in a distorted square-planar coordination environment.The S-Cu-N chelating angle is of 84.41 (5)°.The Cu(II) atom is located on a crystallographic inversion centre, leading to a trans configuration of the N,S-chelating ligands.

In the title complex, [Cu(C16H24N3S2)2], the Cu(II) atom is coordinated by two azomethine N and two thiol-ate S atoms of the chelating Schiff base ligands, resulting in a distorted square-planar coordination environment. The S-Cu-N chelating angle is of 84.41 (5)°. The Cu(II) atom is located on a crystallographic inversion centre, leading to a trans configuration of the N,S-chelating ligands.

Mentions: In the crystal, the bis-chelated CuII complex resides on a crystallographic inversion centre and the two chelating Schiff bases, in their deprotonated imino thiol­ate form, coordinate the metal centre via the azomethine nitro­gen N1 and thiol­ate sulfur S1 atoms in a trans-planar configuration (Fig. 1 ▶). The Cu1—S and Cu1—N coordination bond lengths are of 2.2557 (6) and 2.0060 (14) Å, respectively, with an S1—Cu—N1 chelating angle of 84.41 (5)°. It is worth of note that copper(II) complexes with similar di­thio­carbazate ligands assume a distorted tetra­hedral configuration as well (Tarafder, et al., 2008 ▶; Manan, et al., 2011 ▶). In these derivatives the coordination distances are close comparable to those here reported. On the other hand the present Cu—S and Cu—N bond lengths are slightly longer with respect to those measured in the centrosymmetric complex with ligand bearing a benzyl group at the S atom [Cu—S = 2.165 (1), Cu—N = 1.929 (4) Å; Tian, et al., 1998 ▶).
