The title compound, C 14 H 13 N 3 O 2 ÁH 2 O, is a new orthorhombic polymorph of a structure reported previously [Jing, Fan, Yu, Chen & Deng (2005). Acta Cryst. E61, o3208-o3209]. The crystal structure is stabilized by a network of N-HÁ Á ÁO and O-HÁ Á ÁN hydrogen bonds linking three molecules to ea
