Abstract
In the title compound, [CrBr(2)(C(5)H(14)N(2))(2)](2)Br(2).HClO(4).6H(2)O, there are two independent Cr(III) complex cations which are conformational isomers of each other. The Cr atoms lie respectively on a center of symmetry and on a mirror plane and have octahedral environments, coordinated by the N atoms of two 2,2-dimethylpropane-1,3-diamine ligands and by two Br atoms in trans positions. The Cr-N and Cr-Br bond lengths are in the ranges 2.078 (3)-2.089 (3) and 2.4495 (9)-2.5017 (9) A, respectively. The crystal structure consists of two Cr(III) complex cations, two Br(-) anions, a (ClO(4))(-) anion and an [H(13)O(6)](+) hydrogen-bonded cluster cation.
