Crystal structure and Hirshfeld surface analysis of a zinc xanthate complex containing the 2,2'-bipyridine ligand.

In the title compound, (2,2′-bi­pyridine-κ²N,N′)bis­(2-meth­oxy­ethyl xanthato-κS)zinc(II), [Zn(C4H7O2S2)2(C10H8N2)], the ZnII ion is coordinated to two N atoms of the 2,2′-bi­pyridine ligand and two S atoms from two 2-meth­oxy­ethyl xanthate ligands. The ZnII ion lies on a crystallographic twofold rotation axis and has distorted tetra­hedral coordination geometry. In the crystal, mol­ecules are linked by weak C—H· · ·O hydrogen bonds, forming supramolecular chains propagating along the a-axis direction. Weak intra­molecular C—H· · ·S hydrogen bonds are also observed. The inter­molecular contacts in the crystal were further analysed using Hirshfield surface analysis, which indicates that the most significant contacts are H· · ·H (36.3%), followed by S· · ·H/H· · ·S (24.7%), C· · ·H/H· · ·C (15.1%), O· · ·H/H· · ·O (14.4%), N· · ·H/H· · ·N (4.1%) and C· · ·C (2.9%).
