title: (5Z)-4-Amino-2-(4-hydroxyphenyl)-1H-imidazol-5(2H)-one oxime 3-oxide.
abstract: The title molecule, C(9)H(10)N(4)O(3), consists of benzene and imidazole rings which are almost perpendicular to each other. A hydroxyimino group is directly linked to the imidazole ring with a double C=N bond, which is the first example in this type of compound. The double bond may be a good location for the initiation of various reactions with a wide range of potential applications. In the crystal structure, there are pi-pi interactions between molecules related by a centre of symmetry, with the imidazole and benzene rings almost completely overlapped. The molecules are hydrogen bonded in each direction and form a three-dimensional hydrogen-bond network.
