Chlorido-bis--(ethane-1,2-di-amine)(4H-1,2,4-triazole-κN1)cobalt(III) dichloride

摘要

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) A? , while the Co—Cl bond length is 2.257 (1) A? . In the crystal, molecules are linked by N— HN, N—HCl and C—HCl hydrogen bonds. Dimers are formed by N— HCl hydrogen-bonding interactions between amine H-atom donors and chloride ions resulting in an R4 2 (8) ring motif. These dimers are further connected in a head-to-tail fashion via N—HCl and C—HCl hydrogen bonds. All the interactions together combine to link the molecules into a threedimensional framework.
