N'-[(Z)-4-(Dimethyl-amino)benzyl-idene]-4-nitro-benzohydrazide mono-hydrate.

ABSTRACT: In the asymmetric unit of the title compound, C(16)H(16)N(4)O(3)·H(2)O, there are two symmetry-independent hydrazide mol-ecules with almost identical geometries, and two independent water mol-ecules. The dihedral angles between the two benzene rings in the two hydrazide mol-ecules are 0.11?(5) and 0.77?(5)°. In one mol-ecule, an intra-molecular C-H?O hydrogen bond generates a ring of graph-set motif S(5). Inter-molecular N-H?O, O-H?O, O-H?N and C-H?O hydrogen bonds and ?-? stacking inter-actions between the benzene rings [centroid-centroid distances in the range 3.5021?(6)-3.6403?(6)?Å] are observed, together with O?O [2.7226?(11)?Å], O?N [2.7072?(10)?Å] and N?O [2.7072?(10)-2.8582?(12)?Å] short contacts. The hydrazine mol-ecules are stacked along the b axis and adjacent mol-ecules are linked by water mol-ecules.
