The title complex, [Cu(C26H22N2O4)], is isostructural with its Ni analogue. All intramolecular distances and angles are very similar for the two structures, whereas the packing of the molecules, including C—H⋯O and C—H⋯π interactions, are slightly different.

A solution of Cu(II) acetate monohydrate (1.7 mg, 0.0085 mmol) in ethanol (5 ml) was added dropwise to a solution of 2,2'-[1,1'-ethylenedioxybis(nitriloethylidyne)]dinaphthol (3.4 mg, 0.0079 mmol) in dichloromethane (5 ml). The colour of the mixing solution turns to brown, immediately, and was allowed to stand at room temperature for about one week, the solvent was partially evaporated and obtained dark-brown needle-like single crystals suitable for X-ray crystallographic analysis.
H atoms were treated as riding atoms with distances C—H = 0.96 (CH3), C—H = 0.97 (CH2), or 0.93 Å (CH), and Uiso(H) = 1.2 Ueq(C) and 1.5 Ueq(Cmethyl).

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. |

Transition metal complexes with multidentate salen-type ligands are very interesting in modern coordination chemistry because they have mono-, di- or tri-nuclear metal complexes with important stereochemistry (Katsuki et al., 1995; Akine et al., 2005; Dong et al., 2009b). Metal derivatives of salen-type compounds have been investigated extensively, and copper(II) complexes play a major role in both synthetic and structural research (Ray et al., 2003; Dong et al., 2009a).
In this paper, a new mononuclear copper(II) complex with salen-type bisoxime chelating ligand, 2,2'-[1,1'-ethylenedioxybis(nitriloethylidyne)]dinaphthol, has been synthesized (Sun et al., 2008). The X-ray crystallography of the title complex (Fig. 1) reveals the complex crystallizes in the monoclinic system, with P21/c space group. There is a crystallographic twofold screw axis (symmetry code: 1/2 - x, 1/2 + y, 1/2 - z). The dihedral angle between the coordination plane of O3—Cu1—N1 and that of O4—Cu1—N2 is 26.53°, indicating slight distortion toward tetrahedral geometry from the square planar structure [Cu1—O3: 1.876 (3) Å; Cu1—O4: 1.895 (3) Å; Cu1—N1: 1.976 (3) Å; Cu1—N2: 1.947 (3) Å]), with a mean deviation of 0.016 Å from the N2O2 plane. The crystal structure is further stabilized by intermolecular C16—H16A···O3, C23—H23···O2 hydrogen bonds and C4—H4C···π interactions (Table 1), which link neighbouring molecules into extended chains along the c axis.
