The monoclinic form of 1,4,8,11-tetraazacyclotetradecanecopper(II) tetrachlorocuprate, [Cu(14-ane)]CuCl4, has a chain structure consisting of Cu(14-ane)(2+) cations linked by CuCl42- anions. The Cu-II ion has square-planar coordination in the cation [average Cu-N distance = 2.020 (7) Angstrom] while the anion has Battened tetrahedral coordination geometry [average Cu-Cl distance = 2.246 (13) Angstrom with average trans Cl-Cu-Cl angles = 130 (1) degrees]. The cations and anions are linked by semi-coordinate Cu ... Cl bonds with a distance of 2.855 (2) Angstrom to form chains which run parallel to the c axis and pack in a hexagonal array.
