In the title compound, [Cu(C19H20N2O4)(H2O)]·C2H3N, the CuII ion is coordinated by two N and two O atoms from the tetradentate Schiff base ligand, which contains a propylene fragment disordered over two conformations in a 0.64 (1):0.36 (1) ratio, and one O atom from the water molecule in a distorted square-pyramidal geometry. In the intermolecular O—H⋯O hydrogen bonds link the molecules into chains along the a axis.

The Schiff base ligand was synthesized by condensation of propyl diamine and 3-methoxyl-2-hydroxy-benzaldehyde with the ratio 1:2 in ethanol. The title complex was synthesized by reacting Cu(ClO4)2.6H2O and the schiff-base ligand (1:1, molar ratio) in acetonitrile. The mixture was stirred for for about 10 min at room temperature, then filtered, and then the filtrate was allowed to slow evaporate undisturbed for ten days to afford blue crystals suitable for X-ray diffraction with a yield about 60%.
C-bound H atoms were geometrically positioned with C—H distances of 0.93, 0.96 and 0.97 Å, respectively, and were refined as riding, with Uiso(H) = 1.2Ueq(C). For the H atom of the water molecule, they were found from difference Fourier maps, but placed in idealized positions with O—H = 0.82 Å, and refined as riding, with Uiso(H) = 1.5Ueq(O). Thepropylene fragment was disordered between two conformations with the occupancies refined to 0.64 (1) and 0.36 (1), respectively.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In continuation of our studies of tetradentate Shiff-base ligands and their complexes (Xing, 2009), we present here the title compound, (I).
In (I) (Fig. 1), the coordination sphere of the CuII ion can be described as a distorted square-pyramidal one, in which the four basal positions are occupied by two N atoms and two O atoms from the tetradentate Schiff-base ligand, and the fifth apical site is occupied by the O atom of the coordinated water molecule. The CuII ion is out of the plane formed by N2O2 unit at 0.102Å towards the Cu—OH2O bond. The average Cu—N, Cu—OSchiff base, and the Cu—Oaqua bond lengths are 2.017 (4), 1.956 (4) and 2.276 (4) Å, respectively, which are all in agreement with the corresponding distances found in others Schiff base complexes with Cu (Nathan, et al., 2003; Saha, et al., 2007; Xing, 2009).
