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

Abstract

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%).
