Abstract top

The title compound, {[Cu2(C17H11N3O)(SO4)(C5H5N)2]·0.5C4H10O}n, was synthesized by the reaction of 2-hydroxy-1-naphthylaldehyde-2-pyridinecarboxylhydrazone with copper sulfonate. A one-dimensional polymer was obtained via self-assembly. Each Cu ion is located in a distorted square-pyramidal coordination environment, with one Cu ion coordinated by two N and three O atoms, while the other links to two O and three N atoms. In the crystal, weak intermolecular C-H...O interactions connect the chains into a two-dimensional network.

Comment top

Hydrazone complexes play an important role in the fields of photoelectric materials and medicines due to their biological and pharmacological activities (Armstrong et al., 2003). The molecular structure of the related salicylaldehyde-2-pyridinecarboxyl-hydrazone has been reported (Bai et al., 2006). To throw further light on the coordination characteristics of 2-pyridinecarboxyl-hydrazone and to explore the properties of their complexes, we report the structure of the title complex (I).

The structure of repeating unit of complex I is shown in Fig. 1 and the one-dimensional polymeric chain structure of the complex is shown in Fig. 2. In the complex, each Cu ion is located in a distorted square pyramidal coordination environment. Cu1 is coordinated to two N and three O atoms, while Cu2 links to two O and three N atoms. The Cu—O (2-naphthol) distance [1.888 (3) Å] is slightly shorter than the previously reported Cu—O (phenol) distance [1.954 (3) Å] (Bai et al., 2006), whereas the Cu—O (carbozone) distance [1.964 (3) Å] is longer than the related Cu—O (carbozone) distance of 1.942 (3) Å in the related complex (Bai et al., 2006). In the crystal, weak intermolecular C—H···O interactions connect the chains into a two-dimensional net structure.

Experimental top

The title compound was synthesizd by mixing 2-hydroxy-1-naphthylaldehyde-2-pyridinecarboxyl-hydrazone (0.0291 g, 0.1 mmol) and copper sulfonate (0.0319 g, 0.2 mmol) and stirring in 10 ml of pyridine for 6 h. The product was filtered and then layered with ether. 2 weeks later brown single crystals were obtained. Anal.

Special details top

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.
