Abstract

In the title dinuclear copper complex, [Cu(2)Cl(4)(C(29)H(34)N(6))]·1.5H(2)O, both Cu(II) ions are coordinated in a slightly distorted square-pyramidal environment in which the N atoms of the dipicolyl-amine group and a chloride ligand form the basal plane. The apical position is occupied by a second chloride atom. The Cu-N distances involving the pyridine N atoms differ slightly from each other and the Cu-N distance involving the tertiary N atom is the longest. The apical Cu-Cl distance is elongated compared to its basal counterpart due to typical Jahn-Teller distortion. In the crystal structure, complex and water mol-ecules are linked via inter-molecular O-H⋯O and O-H⋯Cl hydrogen bonds into chains along [001]. One of the water mol-ecules was refined with half occupancy.
