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.

The title compound, C6H5N3S3, consists of two biologically relevant heterocyclic units, suggesting potential biological activity and possible use as a ligand in metal complexation. The compound crystallizes in the monoclinic space group P21/c and features non-classical inter­molecular C—H⋯N hydrogen bonds, along with π–π stacking inter­actions that contribute to the crystal cohesion. Hirshfeld surface analysis highlights significant inter­molecular inter­actions including, among others, N⋯H/H⋯N, S⋯H/H⋯S, and S⋯C/C⋯S contacts.
