We have prepared a series of benzamide / zinc(II)chloride ionic cocrystals and characterized them by infrared spectroscopy, powder X-ray diffraction and single-crystal X-ray diffraction. In each case examined to date, the amide forms a 2:1 complex with zinc chloride via coordination of the amide oxygen to the zinc center. A variety of hydrogen bonding patterns are observed, including both intra- and intermolcular interactions and a combination of N-H...O and N-H...Cl contacts. The type of interaction observed appears to be determined in part by steric effects.
