The hydrazone mol-ecule in title monohydrate, C(14)H(13)N(3)O(4)·H(2)O, is almost coplanar, the dihedral angle between the terminal benzene rings being 3.22 (15)°; the nitro group is coplanar with the benzene ring to which it is bonded [O-N-C-C = -2.8 (4)°]. The hy-droxy group forms an intra-molecular hydrogen bond with the imine N atom, and the conformation about the imine bond [1.305 (3) Å] is E. In the crystal, supra-molecular layers in the (203) plane are connected into a double layer via water-nitro O-H⋯O hydrogen bonds, along with π-π inter-actions [ring centroid-centroid distance = 3.7859 (19) Å].
标题一水合物C(14)H(13)N(3)O(4)·H(2)O中的腙分子几乎共面，末端苯环之间的二面角为3.22 (15)°；硝基与它所连接的苯环共面[O-N-C-C = -2.8 (4)°]。羟基与亚胺N原子形成分子内氢键，亚胺键[1.305 (3) Å]的构象为E型。在晶体中，(203)平面上的超分子层通过水-硝基O-H⋯O氢键以及π-π相互作用[环质心-质心距离 = 3.7859 (19) Å]连接成双层。
