摘要:
The structure of {3-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-ylidene}{1-[2-(4-methoxyphenyl)ethyl]-4-piperidin-1-io}ammonium tetrachlorocuprate(II), (C28H33FN4O)[CuCl4], contains diprotonated cations of astemizole hydrogen bonded to three Cl atoms in two different CuCl42- anions, with Cl . . . N distances in the range 3.166 (4)-3.203 (4) Angstrom. The geometry around copper is flattened tetrahedral with significantly different Cu-Cl distances which lie in the range 2.1968 (14)-2.2861 (12) Angstrom. The phenylethyl C atoms of the (4-methoxyphenyl)ethyl group are disordered indicating the presence of two conformers in the crystals.
