The title compound was synthesized by adding bis(hydroxy naphtylidene)-1,4-butanediamine (2 mmol) to a solution of CuCl2. 4 H2O (2 mmol) in ethanol (30 ml). The mixture was refluxed with stirring for half an hour. The resultant green solution was filtered. Dark-green block single crystals of the title compound suitable for X-ray
were recrystallized from ethanol by slow evaporation of the solvents at room temperature over several days.All hydrogen atoms were positioned geometrically with C—H = 0.93-0.97 Å and included in a riding model approximation with Uiso (H) = 1.2 or 1.5 Ueq (C). The H atom of the hydroxy group was located from the difference Fourier mapand constrained to refine with the parent atom with Uiso (H) = 1.5 Ueq (O) after its distance was restrained to 0.90 (1)Å.
Schiff base complexes are one of the most important stereochemical models in transition metal coordination chemistry, with the ease of preparation and structural variations (Granovski et al., 1993). Metal derivatives of the
have been studied extensively, and Ni(II) and Cu(II) complexes play a major role in both synthetic and structurel research (Kargar et al., 2010; Elmali et al., 2000; Blower et al., 1998).The π–π interactions [Cg1···Cg1i = 3.4852 (18) Å, (i) 2 - x, y, 1/2 - z; Cg2···Cg2i = 3.7183 (6)Å; Cg3···Cg3i = 3.638 (2)Å; Cg4···Cg4i = 3.845 (3)Å], Cg1, Cg2, Cg3 and Cg4 are the centroids of the Cu1/O1/C1/C10/C11/N1, Cu1/O2/C26/C17/C16/N2, C17/C18/C23/C24/C25/C26, and C18–C23 rings, respectively.

The geometry ground the Cu(II) atom is distorted square-planar which is coordinated by the N2O2 donor atoms of the desired potentially tetradenate Schiff base ligand. The dihedral angle between the two aromatic rings is 48.16 (13)°.

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. |

Schiff base complexes are one of the most important stereochemical models in transition metal coordination chemistry, with the ease of preparation and structural variations (Granovski et al., 1993). Metal derivatives of the Schiff bases have been studied extensively, and Ni(II) and Cu(II) complexes play a major role in both synthetic and structurel research (Kargar et al., 2010; Elmali et al., 2000; Blower et al., 1998).
The asymmetric unit of the title compound, Fig. 1, comprises one unit of the Schiff base complex and an ethanol molecule of crystallization. The bond lengths (Allen et al., 1987) and angles are within the normal ranges. The geometry ground the Cu(II) atom is distorted square-planar which is coordinated by the N2O2 donor atoms of the desired potentially tetradenate Schiff base ligand. The dihedral angle between the two aromatic rings is 48.16 (13)°. The crystal structure is stabilized by the intermolecular O—H···O and C—H···O hydrogen bonds and intermolecular π–π interactions [Cg1···Cg1i = 3.4852 (18) Å, (i) 2 - x, y, 1/2 - z; Cg2···Cg2i = 3.7183 (6)Å; Cg3···Cg3i = 3.638 (2)Å; Cg4···Cg4i = 3.845 (3)Å], Cg1, Cg2, Cg3 and Cg4 are the centroids of the Cu1/O1/C1/C10/C11/N1, Cu1/O2/C26/C17/C16/N2, C17/C18/C23/C24/C25/C26, and C18–C23 rings, respectively.
