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(CH<sub>5</sub>N<sub>3</sub>S)<sub>3</sub>][Co(C<sub>6</sub>H<sub>6</sub>O<sub>7</sub>)<sub>2</sub>]<sub>0.5</sub>(NO<sub>3</sub>)<sub>2</sub>·2H<sub>2</sub>O, designated as [Co(tsc)<sub>3</sub>]<sub>2</sub>[Co(cit)<sub>2</sub>](NO<sub>3</sub>)<sub>4</sub>·4H<sub>2</sub>O, 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.

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.

Abstract

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(CH<sub>5</sub>N<sub>3</sub>S)<sub>3</sub>][Co(C<sub>6</sub>H<sub>6</sub>O<sub>7</sub>)<sub>2</sub>]<sub>0.5</sub>(NO<sub>3</sub>)<sub>2</sub>·2H<sub>2</sub>O, designated as [Co(tsc)<sub>3</sub>]<sub>2</sub>[Co(cit)<sub>2</sub>](NO<sub>3</sub>)<sub>4</sub>·4H<sub>2</sub>O, 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.
