cis-Bromido-(n-butyl-amine-κN)bis-(ethene-1,2-di-amine-κ2N,N′)cobalt(III) dibromide

摘要

In the title compound, [CoBr(C 2 H 8 N 2 ) 2 (C 4 H 11 N)]Br 2 , the cobalt(III) ion has a distorted octa-hedral coordination environment and is surrounded by four N atoms in the equatorial plane made up of three N atoms from the two ethyl-enedi-amine ligands and the remaining N from the n -butyl substituent, with the other N atom from the ethyl-enedi-amine ligand and the Br atom occupying the axial positions. In the crystal, the complex cation and the two counter-anions are linked via N—H?Br and C—H?Br hydrogen bonds, forming a three-dimensional network. The crystal studied was refined as a two-component inversion twin.
