Synthesis, crystal structure and Hirshfeld surface analysis of a zinc(II) coordination polymer of 5-phenyl-1,3,4-oxadiazole-2-thiolate
Аннотация
A new zinc coordination polymer with 5-phenyl-1,3,4-oxadiazole-2-thiolate, namely, catena -poly[zinc(II)-bis(μ 2 -5-phenyl-1,3,4-oxadiazole-2-thiolato)-κ 2 N 3 : S ;κ 2 S : N 3 ], [Zn(C 8 H 5 N 2 OS) 2 ] n , was synthesized. The single-crystal X-ray diffraction analysis shows that the polymeric structure crystallizes in the centrosymmetric monoclinic C 2/ 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...H, C...H and S...H. Interactions including N...H, O...H and C...C contacts were also observed; however, their contribution to the overall stability of the crystal lattice is minor.
