Bromido(meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-1,7-diene)copper(II) bromide dihydrate

Abstract

There are two formula units (Z′ = 2) in the asymmmetric unit of the title compound, [CuBr(C16H32N4)]Br·2H2O. The title crystal consists of two [Cu(C16H32N4)]2+ cations, two Br− anions and four uncoordinated water molecules. 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.
