Bis[trans-dibromo(2,2-dimethyl-propane-1,3-diamine-κ2N,N′)chromium(III)] dibromide hydrogen perchlorate hexahydrate

In the title compound, [CrBr2(C5H14N2)(2)](2)Br-2.HClO4.6H(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) Angstrom, respectively. The crystal structure consists of two Cr-III complex cations, two Br- anions, a (ClO4)(-) anion and an [H13O6](+) hydrogen-bonded cluster cation.
