title: Tris(propionitrile-κN)[1,4,7-tris-(cyano-meth-yl)-1,4,7-triaza-cyclo-nonane-κN,N,N]copper(II) bis-(perchlorate) dihydrate.
abstract: 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) octa-hedral environment by three tertiary amines from the tridentate chelating aza-macrocyclic ligand and three propionitrile mol-ecules. Inter-molecular non-classical C-H⋯N hydrogen bonding inter-links the [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](2+) cations into a two-dimensional supra-molecular sheet extending along the ab plane. The crystal packing also exhibits weak C-H⋯O inter-actions.
