Abstract top

The asymmetric unit of the title compound, {[Cu(C13H15NO3)(C5H8N2)]·CH3OH}n, contains two complex molecules and two solvent molecules. Each CuII ion is in a distorted square-pyramidal coordination with one N and two O atoms from the Schiff base ligand and one N atom from the heterocycle in the basal positions and one carboxylate O atom from a neighbouring ligand in the apical position. The apical Cu-O bonds are much longer than the basal Cu-O and Cu-N bonds. The carboxylate groups of the Schiff base ligands bridge the CuII ions, forming helical chains along [100]. The crystal packing is stabilized by intermolecular O-H...O and N-H...O hydrogen bonds.

Comment top

In the past decades, significant progress has been achieved in understanding the chemistry of transition metal complexes with Schiff base ligands composed of salicylaldehyde, 2-formylpyridine or their analogues, and α-amino acids (Vigato & Tamburini, 2004; Ganguly et al., 2008; Casella & Guillotti, 1983). A few stuctural studies have been performed on Schiff base complexes derived from 2-hydroxyacetophenone and animo acids (Basu Baul et al., 2007; Parekh et al., 2006; Zhao et al., 2008, 2009). We report here the crystal structure of the title CuII complex, [Cu(C13H15NO3)(C5H8N2)].CH3OH.

The asymmetric unit of the polymeric title compound consists of two CuII complex molecules and two solvate methanol molecules (Fig. 1). Each of the two CuII ions has a square-pyramidal coordination where the four basal positions are occupied by an O,N,O, donor set from the tridentate Schiff base ligand and the fourth position occupied by one N atom from the 3,5-dimethylpyrazole ligand. The apical position is occupied by a carboxylate O atom from the adjacent tridentate Schiff base ligand. The apical Cu···O bonds are much longer than the basal Cu···O and Cu···N bonds (Table 1). The closest distance between neighbouring CuII ions are 5.803 (6) Å and 5.890 (6) Å, respectively.

The crystal structure is stabilized by intermolecular N—H···O hydrogen bonds between the pyrazole N—H groups as donors and the carboxylate O atoms as acceptors. Additional O—H···O hydrogen bonding involving the methanol solvent molecules is also observed (Table 2 and Fig. 2).

Experimental top

The title compound was synthesized as described in the literature (Plesch et al., 1997). To L-valine (1.00 mmol) and potassium hydroxide (1.00 mmol) in 10 ml of methanol was added 2-hydroxyacetophenone (1.00 mmol in 10 ml of methanol) dropwise. The yellow solution was stirred for 2.0 h at 333 K. The resultant mixture was added dropwise to copper(II) acetate monohydrate (1.00 mmol) and 3,5-dimethylpyrazole (1.00 mmol) in an aqueous methanolic solution (20 ml, 1:1 v/v), and heated with stirring for 2.0 h at 333 K. The dark blue solution was filtered and left for several days. Blue crystals had formed that were filtered off, washed with water, and dried under vacuum.

Refinement top

All H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 or 0.98 Å (CH) and Uiso(H) = 1.2Ueq(C), C—H = 0.96 Å (CH3) and Uiso(H) = 1.5Ueq(C), with N—H = 0.86 Å and Uiso(H) = 1.2Ueq(N), and with O—H = 0.82 Å and 0.85 Å and Uiso(H) = 1.5Ueq(O).

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.
