Abstract

The crystal structure of the title compound was determined by single crystal X-ray diffraction. It consists of molecules of benzohydroxamic acid, its <i>O</i>-deprotonated anions and lithium cations in the 1 : 1 : 1 molar ratio. Although the molecular geometry of the anion is very similar to that of the acid, these units can be unambiguously distinguished since the short hydrogen bond between the OH group of the acid and the <i>N-</i>bonded oxygen atom of the anion is remarkably asymmetric. This bond, together with the lithium cations (being surrounded by five oxygens), links the units into chains running in the crystallographic <i>ab </i>plane. The coordination polyhedron around Li represents a rare example of an almost undistorted LiO<sub>5</sub> square pyramidal arrangement.
