Abstract

Each Cu atom in the dinuclear centrosymmetric title complex, [Cu2Br2(C14H17N3)2](ClO4)2, is ligated in a distorted square-pyramidal geometry (τ = 0.31) by a tridentate bis[2-(2-pyridyl)ethyl]amine ligand, and by two bridging Br atoms. In addition, the dinuclear species is stabilized by two hydrogen-bonded perchlorate anions.
