Abstract
The title compound, C(24)H(20)N(2)O(4)·H(2)O, crystallizes with half a mol-ecule of 2-(naphthalen-2-yl-oxy)-N'-[2-(naphthalen-2-yl-oxy)acet-yl]acetohydrazide and half a water mol-ecule in the asymmetric unit. In the crystal, mol-ecules form planes parallel to (011). Two mol-ecules are connected by water mol-ecules via O-H⋯O and N-H⋯O hydrogen bonds.
