A new zinc coordination polymer with 5-phenyl-1,3,4-oxa­diazole-2-thiol­ate, namely, catena-poly[zinc(II)-bis­(μ2-5-phenyl-1,3,4-oxa­diazole-2-thiol­ato)-κ2N3:S;κ2S:N3], [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 ZnII 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 ZnII 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.

A new cobalt complex, bis­[tris­(amino­thio­urea)cobalt(III)] bis­[2-(carb­oxy­methyl)-2-hy­droxy­butane­dioato]cobalt(II) tetra­nitrate tetra­hydrate, [Co(CH5N3S)3][Co(C6H6O7)2]0.5(NO3)2·2H2O, designated as [Co(tsc)3]2[Co(cit)2](NO3)4·4H2O, was synthesized. Two crystallographically independent cobalt centers are present. In the first, the central metal atom is chelated by three thio­semicarbazide ligands in a bidentate fashion whereas the second, positioned on a crystallographic inversion center, is hexa­coordinated by two citrate anions in a distorted octa­hedral geometry. Additionally, two water mol­ecules and two nitrate anions are present in the asymmetric unit. Hirshfeld surface analysis revealed that the presence of numerous donor and acceptor groups in the complex, which facilitate hydrogen-bonding inter­actions that contribute significantly to the overall cohesion of the crystal structure.
