Abstract

In the title compound, [CuBr2(C8H22N4)], the CuII atom is six-coordinate forming a distorted octa­hedral complex and is bonded to two axial bromide anions and four equatorial nitro­gen donors. The equatorial Cu—N bond distances range from 2.005 (8) to 2.046 (8) Å while the axial Cu—Br distances are 2.8616 (17) and 2.9402 (17) Å, thus the six-coordinate Cu complex shows the usual Jahn–Teller distortion. All amine hydrogen atoms participate in either inter- or intra­molecular hydrogen bonding to the Br anions.
