The title compound, [Cu(C13H16NO2)2], is a mononuclear copper(II) complex derived from the Schiff base ligand 2-(cyclo­pentyl­imino­meth­yl)-5-meth­oxy­phenol and copper acetate. The CuII atom is four-coordinated by the phenolate O atoms and imine N atoms from two Schiff base ligands, in a highly distorted square-planar geometry. The O- and N-donor atoms are mutually trans and the dihedral angle between the two benzene rings is 55.8 (3)°.

Comment top

Schiff bases are known to be versatile ligands in coordination chemistry (Hamaker et al., 2010; Wang et al., 2010; Mirkhani et al., 2010; Liu & Yang, 2009). A large number of complexes with Schiff bases have been reported because of their interesting structures and potential applications (Keypour et al., 2009; Adhikary et al., 2009; Peng et al., 2009). We report here the crystal structure of the title new copper complex with the Schiff base ligand 2-(cyclopentyliminomethyl)-5-methoxyphenol.

The Cu atom in the complex is four-coordinated by two phenolate O atoms and two imine N atoms from two Schiff base ligands, forming a distorted square planar geometry (Fig. 1). The dihedral angle between the C1-C6 and C14-C19 benzene rings is 55.8 (3)°. The bond lengths (Table 1) involving the Cu atom are comparable to those observed in similar copper complexes (Friščić et al., 2002; Marsh & Spek, 2001; Han et al., 2001; Akitsu & Einaga, 2004; Dhar et al., 2003).

Experimental top

4-Methoxysalicylaldehyde (0.1 mmol, 15.2 mg) and cyclopentylamine (0.1 mmol, 8.5 mg) were mixed and stirred in methanol (10 ml) for 30 min. Then a methanol solution (5 ml) of copper acetate (0.1 mmol, 19.9 mg) was added to the mixture. The final mixture was stirred for another 30 min to give a blue solution. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of the solution at room temperature.

Refinement top

H atoms were positioned geometrically (C—H = 0.93–0.97 Å) and refined using a riding model, with with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(Cmetyl). Rotating group models were used for the methyl groups.

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.
