In the title compound, [Cu(C(13)H(20)N(3)O)Br], the Cu(II) atom is coordinated by three N atoms and one O atom from the deprotonated ligand derived from the Schiff base condensation of 3,3-imino-bis-(propyl-amine) and salicyl-aldehyde. The three N and the O atoms occupy equatorial positions, while the Br atom occupies an axial position. The amine H atoms form inter-molecular hydrogen bonds with the Br and O atoms of adjoining mol-ecules.
