title: Astemizole tetrachlorocuprate(II).
abstract: The structure of ¿3-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-ylidene¿¿1-[2-(4- methox yphenyl)ethyl]-4-piperidin-1-io¿ammonium tetrachlorocuprate(II), (C(28)H(33)FN(4)O)[CuCl(4)], contains diprotonated cations of astemizole hydrogen bonded to three Cl atoms in two different CuCl(4)(2-) anions, with Cl.N distances in the range 3.166 (4)-3.203 (4) A. The geometry around copper is flattened tetrahedral with significantly different Cu-Cl distances which lie in the range 2.1968 (14)-2.2861 (12) A. The phenylethyl C atoms of the (4-methoxyphenyl)ethyl group are disordered indicating the presence of two conformers in the crystals.
