Abstract

In the mononuclear title compound, [Cu^II(C₁₈H₁₂N₂O₂)(C₅H₅N)], the Cu^II ion is coordinated by two O atoms and one N atom from the dianionic tridentate L ²⁻ ligand (H₂ L is 2-hydroxy-1-naphthaldehyde benzoylhydrazide) and one N atom from a pyridine molecule in a CuN₂O₂ distorted square-planar coordination environment.

Comment

Interest in the chemistry of Schiff base arises from their ability to bind to metal ions (Yu et al., 2010) as well as their antitumor activities and magnetochemistry (Ando et al., 2004; Guo et al., 2010). In fact, with some acylhydrazone ligands, their metal compounds are endowed with significantly improved industrial processes (Anford et al., 1998). We selected the 2-hydroxy-1-naphthaldehyde benzoylhydrazide (H₂L) Schiff base ligand to construct coordination polymers with defined geometry, due to its combination of nitrogen and oxygen donor atoms. We report here the preparation and crystal structure of the Schiff base Cu^II title compound.

The present compound, [Cu^II(C₁₈H₁₂N₂O₂)(C₅H₅N)], together with the atom-numbering scheme, is illustrated in Fig. 1. Selected bond lengths and angles are given in Table 1. The Cu^II ion is coordinated by two O atoms and one N atom from the dianionic tridentate ligand L^2- ligand (H₂L is 2-hydroxy-1-naphthaldehyde benzoylhydrazide), and one N atom from a pyridine molecule. The Cu^II ion adopts a CuN₂O₂ distorted square-planar coordination environment. The Cu—O and Cu—N bond distances are similar to the corresponding bond distances observed in related compounds (Ali et al., 2004; Xu et al., 2006; Sun et al., 2011). There is no significant deviation of the metal centre from the N₂O₂ equatorial plane. The maximum displacements from the least-squares plane through N1, N3, O1, and O2 (rms deviation = 0.0895 Å) are 0.096 (1) and -0.094 (1) Å for atoms N1 and O2; Cu1 is -0.013 (1) Å below the mean plane. The coordinated pyridine molecule is almost coplanar with the previous N₂O₂ plane, the dihedral angle between the mean planes is 7.2 (1)°.

Experimental

The 2-hydroxy-1-naphthaldehyde benzoylhydrazide ligand (H₂L) was prepared in a similar manner to the reported procedures (Qiao et al., 2010). The title compound was synthesized by adding pyridine (0.2 mL) to a solution of H₂L (0.1 mmol) and Cu(OAc)₂ (0.1 mmol) in methanol/dichloromethane (1:1, 20 mL), and the resulting mixture was stirred for about 6 h to afford a green solution. A week later, brown crystals of the title compound were isolated from the solution.

Special details

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.
