A new cobalt complex, bis-[tris-(amino-thio-urea)cobalt(III)] bis-[2-(carb-oxy-methyl)-2-hy-droxy-butane-dioato]cobalt(II) tetra-nitrate tetra-hydrate, [Co(CH5N3S)3][Co(C6H6O7)2]0.5(NO3)2{\textperiodcentered}2H2O, designated as [Co(tsc)3]2[Co(cit)2](NO3)4{\textperiodcentered}4H2O, was synthesized. Two crystallographically independent cobalt centers are present. In the first, the central metal atom is chelated by three thio-semicarbazide ligands in a bidentate fashion whereas the second, positioned on a crystallographic inversion center, is hexa-coordinated by two citrate anions in a distorted octa-hedral geometry. Additionally, two water mol-ecules 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 inter-actions that contribute significantly to the overall cohesion of the crystal structure.
