Astemizole tetrachlorocobaltate(II)

M. Parvez

Abstract: The structure of {3-[(4-fluorophenyl)methyl]-1H-benzimidazol-2-ylidene}{1-[2-(4-methoxyphenyl)ethyl]-4-piperidin-1-io}ammonium tetrachlorocobaltate(II), (C₂₈H₃₃FN₄O)[CoCl₄], is isomorphous with its CuCl₄^2- analogue. It contains diprotonated cations of astemizole hydrogen-bonded to three Cl atoms in two different CoCl₄^2- anions, with ClN distances in the range 3.109  (5)-3.212  (5)  Å. One of the Cl atoms in the CoCl₄^2- anion is disordered and the geometry around cobalt is distorted tetrahedral. The phenylethyl C atoms of the (4-methoxyphenyl)ethyl group attached to the piperidine ring are disordered, indicating the presence of two conformers in the crystal.
