Diaqua(1,4,8,11-tetraazacyclotetradecane-κ4N1,N4,N8,N11)copper(II) didodecanoate dihydrate

Abstract

The title compound, [Cu(C10H24N4)(H2O)2][CH3(CH2)10CO2]2·2H2O, consists of one cationic copper(II) complex, two dodecanoate anions and two water solvent molecules. The CuII atom is located on an inversion center and is chelated by the four aza N atoms of the neutral 1,4,8,11-tetraazacyclotetradecane (cyclam) ligand and by two water molecules in axial positions, giving an octahedral coordination geometry, distorted as a consequence of the Jahn–Teller effect. The uncoordinated water molecules link the complex cations and the dodecanoate counter-ions through O—H...O hydrogen bonding, forming a layer structure parallel to (001). Intermolecular N—H...O interactions also occur.
