Synthesis, crystal structure and Hirshfeld surface analysis of a zinc(II) coordination polymer of 5-phenyl-1,3,4-oxadiazole-2-thiolate

A new zinc coordination polymer with 5-phenyl-1,3,4-oxadiazole-2-thiolate, namely, catena-poly[zinc(II)-bis(mu(2)-5-phenyl-1,3,4-oxadiazole-2-thiolato)-kappa N-2(3):S;kappa S-2:N-3], [Zn(C8H5N2OS)(2)](n), was synthesized. The single-crystal X-ray diffraction analysis shows that the polymeric structure crystallizes in the centrosymmetric monoclinic C2/c space group. The Zn-II atom is coordinated to two S and two N atoms from four crystallographically independent (L) ligands, forming zigzag chains along the [001] direction. This polymer complex forms an eight-membered [Zn-S-C-N-Zn-S-C-N] chair-like ring with two Zn-II atoms and two ligand molecules. On the Hirshfeld surface, the largest contributions come from the short contacts such as van der Waals forces, including H center dot center dot center dot H, C center dot center dot center dot H and S center dot center dot center dot H. Interactions including N center dot center dot center dot H, O center dot center dot center dot H and C center dot center dot center dot C contacts were also observed; however, their contribution to the overall stability of the crystal lattice is minor.
