In the title complex, [Cu(C₂₃H₂₈N₂O₄)]·H₂O, the Cu^II ion has a distorted planar geometry, coordinated by the N₂O₂ unit of the tetradentate Schiff base ligand. The asymmetric unit comprises one complex molecule and a water molecule of crystallization. The water H atoms form bifurcated O—H⋯(O,O) intermolecular hydrogen bonds with the O atoms of the phenolate and ethoxy groups with R₁²(5) and R₁²(6) ring motifs, which may, in part, influence the molecular configuration. The dihedral angle between the two O—Cu—N coordination planes is 31.02 (6)° and the dihedral angle between the two benzene rings is 34.98 (7)°. In the crystal structure, molecules are linked together by intermolecular C—H⋯O interactions, forming extended chains along the a axis. The crystal structure is further stabilized by intermolecular C—H⋯π and π–π [centroid–centroid = 3.5068 (13) Å] interactions.

Comment top

Schiff base complexes are some of the most important stereochemical models in transition metal coordination chemistry, with their ease of preparation and structural variations (Granovski et al., 1993). Metal derivatives of Schiff bases have been studied extensively, and copper(II) and Ni(II) complexes play a major role in both synthetic and structural research (Elmali et al., 2000; Blower, 1998; Granovski et al., 1993; Li & Chang, 1991; Shahrokhian et al., 2000). Tetradentate Schiff base metal complexes may form trans or cis planar or tetrahedral structures (Elmali et al., 2000).

The Cu^II ion of the title compound (Fig. 1), shows a distorted planar geometry which is coordinated by two imine N atoms and two phenol O atoms of the tetradentate Schiff base ligand. The bond lengths (Allen et al.,, 1987) and angles are within normal ranges and are comparable with the related structures (Clark et al., 1968, 1969, 1970). The asymmetric unit of the title compound comprises one molecule of complex and a water molecule of crystallization. The water H atoms form bifurcated O—H···(O,O) intermolecular hydrogen bonds with the O atoms of the phenolato and ethoxy groups with R₁²(5) and R₁²(6) ring motifs (Bernstein et al., 1995), which may, in part, influence the molecular configuration. The dihedral angle between the two benzene rings is 34.98 (7)°. In the crystal structure, the molecules are linked together by intermolecular C—H···O interactions, forming 1-D extended chains along the a axis (Fig. 2). The crystal structure is further stabilized by intermolecular C—H···π (Table 1) and π–π interactions [Cg3···Cg3ⁱ = 3.5068 (13) Å, Cg3 is the centroid of the Cu1/O1/C1/C6/C7/N1 ring, symmetry operation i = 1-x, 1-y, 1-z].

Experimental top

A chloroform solution (40 ml) of [N,N'-Bis(3-ethoxy-salicylidene)-2, 2-dimethyl-1,3-propanediamin (1 mmol, 399 mg) was added to an ethanol solution (20 ml) of CuCl₂.4H₂O (1.05 mmol, 216 mg). The mixture was refluxed for 30 min and then filtered. After keeping the filtrate in air, green plate-shaped crystals were formed at the bottom of the vessel on slow evaporation of the solvent.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1)K.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
