Bis(2-{1-[2-(2-hydroxyethylamino)ethylimino]propyl}phenolato)-1κ4 O,N,N′,O′;2κ4 O,N,N′,O′-methanol-2κO-μ-perchlorato-1:2κ2 O:O′-perchlorato-1κO-dicopper(II)

Abstract

The title compound, [Cu2(C13H18N2O2)2(ClO4)2(CH4O)], consists of two six-coordinate Jahn–Teller-distorted copper(II) complex units with the tetradentate ligand 2-{1-[2-(2-hydroxyethylamino)ethylimino]propyl}phenolate observed in a planar coordination mode. Each copper center has octahedral coordination geometry. The complex units are axially connected by a bridging perchlorate anion. For one copper center, the other axial position is occupied by a terminal methanol molecule, while for the other copper center, the axial position is occupied by a weakly coordinated second perchlorate anion. As well as intermolecular N—H...O hydrogen bonds, the two Cu complex units are also linked by intramolecular O—H...O hydrogen-bonding interactions. The four O atoms of one perchlorate are disordered over four positions; the site occupancy factors are 0.43. 0.25, 0.19 and 0.13.
