Acetonitrile-{3-[bis-(2-pyridyl-methyl-κN)amino-κN]propanol-κO}(perchlorato-κO)copper(II) perchlorate.

In the title compound, [Cu(ClO4)(C2H3N)(C15H19N3O)]ClO4, the CuII ion is coordinated by three N atoms and a hydroxyl-O atom of the tetra­dentate ligand, an O atom of a perchlorate ion and an N atom of an acetonitrile ligand giving a tetra­gonally distorted octa­hedral environment around the copper(II) atom. There is an offset inter-complex face-to-face π–π inter­action [centroid–centroid distance = 3.718 (2) A] involving one of the pyridine rings of the ligand as well as an intra-complex O—H⋯O hydrogen-bonding inter­action between the coordinated hydroxyl group of the ligand and the perchlorate counter-ion.
