| Summary: | In the title complex, [CoIIICl(C2H8N2)2(C2H3N3)]Cl2, the CoIII ion has a distorted octahedral environment. It is surrounded by four N atoms in the equatorial plane, with another N atom and a Cl atom occupying the axial positions. Both five-membered Co—N—C—C—N rings adopt a twist conformation. The Co—N bond lengths range from 1.941 (2) to 1.954 (1) Å, while the Co—Cl bond length is 2.257 (1) Å. In the crystal, molecules are linked by N—H...N, N—H...Cl and C—H...Cl hydrogen bonds. Dimers are formed by N—H...Cl hydrogen-bonding interactions between amine H-atom donors and chloride ions resulting in an R42(8) ring motif. These dimers are further connected in a head-to-tail fashion via N—H...Cl and C—H...Cl hydrogen bonds. All the interactions together combine to link the molecules into a three-dimensional framework.
