cis-Bromidobis(1,2-diaminoethane-κ² N,N′)(ethylamine-κN)cobalt(III) dibromide

Abstract

In the title complex, [CoBr(C2H7N)(C2H8N2)2]Br2, the CoIII centre has a distorted octahedral coordination environment, and is surrounded by four N atoms in the equatorial plane, with an additional N atom and the Br atom occupying the axial positions. The complex is isostructural with the Cl compound for which the X-ray structure has also been reported [Anbalagan, Mahalakshmi & Ganeshraja (2011). J. Mol. Struct. 1005, 45–52]. In the crystal, the complex cation and the two counter-anions are linked via N—H...Br hydrogen bonds, forming a three-dimensional network.
