The asymmetric unit of the title compound, [ZnBr₂(C₁₄H₂₀N₂O)]·H₂O, consists of a mononuclear Schiff base zinc(II) complex molecule and a solvent water molecule. The Zn^II atom is four-coordinated in an approximately tetrahedral geometry, binding to the imine N and phenolate O atoms of the neutral zwitterionic Schiff base ligand and to two terminal Br⁻ anions. In the crystal structure, molecules are linked through intermolecular O—H⋯Br and O—H⋯O hydrogen bonds, forming chains running along the b axis.

Comment top

Zinc(II) complexes derived from Schiff base ligands have been studied extensively due to their interesting structures and wide applications (Lacroix et al., 1996; Chisholm et al., 2001; Jian et al., 2004; Tatar et al., 2002; Bhosekar et al., 2006). Recently, we have reported two Schiff base zinc(II) complexes with bromide ligands (Wei et al., 2007; Zhu et al., 2007). As a continuation of our work on the structures of such complexes, we report herein the crystal structure of the new title complex, (I), which is isostructural with the zinc(II) complex with chloride ligands (Zhang et al., 2008).

The tetrahedral coordination sphere of Zn^II atom in (I) is formed by the imine N and phenolate O atoms of the Schiff base ligand and by two terminal Br^- anions (Fig. 1). The coordinate bond distances (Table 1) are typical and comparable with the values in other similar zinc(II) complexes (Peng & Hou, 2006; Peng et al., 2006; Ma, Gu et al., 2006; Ma, Lv et al., 2006). The O1—Zn1—N1 and O1—Zn1—Br1 bond angles deviate most from ideal tetrahedral geometry with values of 93.91 (11) and 116.12 (8)°, respectively. The other angles in the coordination sphere are in the range 108.84 (9)–113.42 (2)° (Table 1).

In the crystal structure of (I), molecules are linked through intermolecular O—H···Br and O—H···O hydrogen bonds (Table 2), forming chains running along the b axis (Fig. 2).

Experimental top

Compound (I) was obtained by stirring of salicylaldehyde (0.1 mmol, 12.2 mg), 2-piperidin-1-ylethylamine (0.1 mmol, 12.8 mg), and zinc(II) bromide (0.1 mmol, 22.5 mg) in methanol (20 ml) for 30 min at room temperature. The reaction mixture was fitered. Yellow block-shaped single crystals suitable for X-ray diffraction formed from the filtrate after one day.

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.
