title: {2-[(2-Acetyl-hydrazin-1-yl-idene)methyl-κN,O]-6-methoxy-phenolato-κO}(nitrato-κO)copper(II) monohydrate.
abstract: In the title complex, [Cu(C(10)H(11)N(2)O(3))(NO(3))]·H(2)O, prepared from the Schiff base N'-(3-meth-oxy-2-oxidobenzyl-idene)-acetohydrazide, the Cu(II) atom is coordinated by two O atoms and one N atom from the ligand and one O atom from a nitrate group in a distorted square-planar geometry. The Cu(II) atom has a weak inter-action with another O atom of the nitrate group. The two O atoms of the tridentate Schiff base ligand are in a trans arrangement. O-H⋯O and N-H⋯O hydrogen bonds involving the uncoordinated water mol-ecule are observed.
