Tris(propionitrile-κN)[1,4,7-tris(cyanomethyl)-1,4,7-triazacyclononane-κ³N¹,N⁴,N⁷]copper(II) bis(perchlorate) dihydrate

Abstract

In the title compound, [Cu(C3H5N)3(C12H18N6)](ClO4)2·2H2O, the CuII atom lies on a threefold rotation axis and is coordinated in a distorted N6 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(C3H5N)3(C12H18N6)]2+ cations into a two-dimensional supra­molecular sheet extending along the ab plane. The crystal packing also exhibits weak C—H⋯O inter­actions.
