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

In the title compound, (2,2′-bi­pyridine-κ(2) N,N′)bis­(2-meth­oxy­ethyl xanthato-κS)zinc(II), [Zn(C(4)H(7)O(2)S(2))(2)(C(10)H(8)N(2))], the Zn(II) ion is coordinated to two N atoms of the 2,2′-bi­pyridine ligand and two S atoms from two 2-meth­oxy­ethyl xanthate ligands. The Zn(II) 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%).
