چکیده
In the title compound, C(16)H(17)N(3)O(2)·0.5H(2)O, the two hydrazide mol-ecules are approximately planar: the dihedral angles between the two substituted benzene rings are 7.7 (2) and 4.2 (2)°. Both hydrazone mol-ecules exist in a trans geometry with respect to their methyl-idene units. In the crystal, the water mol-ecule lies between the two organic mol-ecules and makes bifurcated O-H⋯(N,O) hydrogen bonds to both of them. The hydrazide mol-ecules form N-H⋯O and O-H⋯O hydrogen bonds, resulting in a three-dimensional network.
