The structure of the title compound, C(15)H(12)N(2)O(4), 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 [010] direction. The oxime group has an E conformation.
