title: Bis(nitrato-κO)(5,7,12,14-tetra-methyl-1,4,8,11-tetra-aza-cyclo-tetra-decane-6,13-diaminium-κN,N,N,N)copper(II) dinitrate tetra-hydrate.
abstract: In the title compound, [Cu(NO(3))(2)(C(14)H(36)N(6))](NO(3))(2)·4H(2)O, the Cu(II) atom, lying on an inversion center, is six-coordinated in a distorted octa-hedral environment by four N atoms from a centrosymmetric 14-membered tetra-aza-cyclo-tetra-decane macrocyclic ligand and two O atoms from two nitrate anions. The supra-molecular network is consolidated by extensive O-H⋯O and N-H⋯O hydrogen-bonding inter-actions.
