Comment top

Schiff base complexes play an important role in antibacterial and catalytic performance, and have attracted widespread interest by researchers (Jiang et al., 2003; Kettmann et al., 1993; Zhang, 2006). Meanwhile, Schiff base complexes containing isoleucine have been studied because they are of great significance in the biological and medical field (Royles et al., 2000; Feng et al., 2007; Li et al., 2006).

The central Cu^II atom is penta-coordinated (Fig.1). The quadratic planar is composed by O1, N2, O3and N1. The Schiff base forms two chelating rings(O1—C1—C2—N1—Cu1 and N1—C7—C8—C9—O3- Cu1) to the Cu^IIatom, with a diheral angle of 19.6 (4)° which is in the range observed for many copper Schiff base complexes. The N3 atom occupies the axial position with a N—Cu length of 2.229 (6) Å, comparing with the equatorial Cu—N bond lengths [Cu1—N1 1.924 (6)Å and N2—Cu1 1.975 (6)Å]. The crystal packing is stabilized by O—H···O hydrogen bonds (Fig. 2).

Experimental top

5-Bromo-2-hydroxy-benzaldehyde(0.5 mmol, 100.5 mg) was dissolved in hot ethanol(5 ml), then a mixture of D,L-isoleucine (0.5 mmol, 65.6 mg) and sodium hydroxide (1.0 mmol, 40 mg) was added. After stirring for 1 h, the copper dinitrate trihydrate(0.5 mmol, 120.8 mg) was added and refluxed for another 2 h. At last, an ethanol solution of Phen(0.5 mmol, 99.1 mg) was dropped gradually into to the reaction mixture and refluxed for further 3 h (Zhang et al., 2003; Zhang et al., 2006). The obtained green solution was filtered and held at room temperature for ten days, whereupon green crystals suitable for X-ray diffraction were obtained (yield: 45.2%, based on Cu).

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.
