title: Bromido(meso-5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-1,7-diene)copper(II) bromide dihydrate.
abstract: There are two formula units (Z' = 2) in the asymmmetric unit of the title compound, [CuBr(C(16)H(32)N(4))]Br·2H(2)O. The title crystal consists of two [Cu(C(16)H(32)N(4))](2+) cations, two Br(-) anions and four uncoordinated water mol-ecules. The metal atom is five-coordinate square pyramidal, with a long apical Cu-Br bond [2.9734 (11) and 2.9229 (11) Å in the two cations]. The two cations form a loosely associated dimer through the formation of hydrogen bonds between both N-H and O-H and Br(-). In addition, there is a network of N-H⋯Br, O-H⋯Br and N-H⋯O hydrogen bonds, leading to the formation of a chain structure.
