Abstract
X-ray analysis of cefmenoxime hemihydrochloride was performed. The asymmetric unit of the crystal consists of one chlorine anion and one protonated and one free cefmen oxime molecule. A part of the free molecule is disordered, and conformational differences are observed among the protonated molecule and the two forms of disordered molecules. Intermolecular forces link two independent molecules of cefmenoxime and a chlorine anion and constitute a three-dimensional network in the crystal.
