The two aromatic parts of the title compound, C(16)H(13)N(3)O(4)·5H(2)O, are connected through a conjugated -CH=N-NH-C(O)- fragment, giving an almost planar mol-ecule. The organic mol-ecules and uncoordinated water mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.
