Abstract:The structure of the title compound, C15H12N2O4, consists of a polymeric arrangement, around inversion centres, of molecules linked through O—H…N and O—H…O hydrogen bonds; there are also intramolecular hydrogen bonds. All these hydrogen-bond interactions result in the formation of infinite chains parallel to the  direction. The oxime group has an E conformation.
