Tris(propionitrile-κN)[1,4,7-tris­(cyano­meth­yl)-1,4,7-triaza­cyclo­nonane-κ(3) N (1),N (4),N (7)]copper(II) bis­(perchlorate) dihydrate

In the title compound, [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](ClO(4))(2)·2H(2)O, the Cu(II) atom lies on a threefold rotation axis and is coordinated in a distorted N(6) octa­hedral environment by three tertiary amines from the tridentate chelating aza­macrocyclic ligand and three propionitrile mol­ecules. Inter­molecular non-classical C—H⋯N hydrogen bonding inter­links the [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](2+) cations into a two-dimensional supra­molecular sheet extending along the ab plane. The crystal packing also exhibits weak C—H⋯O inter­actions.
