(Received 21 December 2009; accepted 6 January 2010; online 9 January 2010)

In the title complex, [Cu(C10H11N2O3)(NO3)]·H2O, prepared from the Schiff base N′-(3-meth­oxy-2-oxidobenzyl­idene)­acetohydrazide, the CuII 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 CuII atom has a weak inter­action 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 mol­ecule are observed.

Comment top

In the title complex, the CuII ion adopts a four-coordinated geometry with the Schiff base coordinated to the metal ion as a uninegative charged tridentate ligand via the carbonyl O atom, the azomethine N atom and the phenolate O atom. The fourth coordination position is occupied by an O atom of the nitrate group. The CuII ion has a weak interaction with another O atom (O6) of the nitrate (Table 1). The bond distances of Cu—N and Cu—O are similar to the other Cu analogue with the same tridentate ligand (Ainscough et al., 1998). The Cu—O(NO3) distance is similar to the observed value for the complex [Cu(L)NO3] [L = 1-(pyridin-2-ylmethyliminomethyl)naphtalen-2-olato] (You & Zhu, 2004). The two O donor atoms of the ligand are in a trans arrangement with an O—Cu—O angle of 173.76 (6)°. The angles around Cu are in a range of 81.49 (7)–173.76 (6)° and sum of the angles at Cu is 360.4°, suggesting that the geometry around the Cu atom is distorted square-planar (Fig. 1).

Experimental top

All purchased chemicals and solvents were reagent grade and used without further purification. The solid-state IR spectra were recorded from KBr discs on a Nicolet spectrophotometer. To a mixture of the ligand (0.211 g, 1.0 mmol) and 20 ml of ethanol was added dropwise a solution of copper nitrate dihydrate (0.242 g, 2.0 mmol) in 10 ml of ethanol. The resulting mixture was stirred under reflux for 2 h. After cooling the solution was filtered and the filtrate was left for slow evaporation. Green crystals of the title compound were obtained in good yield (0.290 g, 82.7%). IR (cm-1): 3403, 1604, 1578, 1445, 1291, 1248, 1082, 1004, 331, 273. Melting point 196±1°C. Analysis, calculated for C10H13CuN3O7: C 34.24, H 3.74, N 11.98%; found: C 34.26, H 3.73, N 16.15%. Single crystals suitable for X-ray analysis were obtained from slow evaporation of a methanol solution of the product.

Refinement top

Water H atoms and amine H atoms of the Schiff base ligand were located from a difference Fourier map and refined as riding atoms with Uiso(H) = 1.2Ueq(N,O). Other H atoms were placed geometrically and refined with a riding model, with C—H = 0.93 (CH) and 0.96 (CH3) Å and with Uiso(H) = 1.2(1.5 for methyl)Ueq(C).
