In the title compound, [Ni(C22H17BrN2O4)]·CH3OH, the NiII ion is in a slightly distorted square-planar geometry involving an N2O2 atom set of the tetradentate Schiff base ligand. The contains one nickel complex and one methanol solvent molecule. The dihedral angle between the aromatic ring planes of the central aromatic ring and other two aromatic rings are 10.8 (3) and 6.0 (2)°. The is stabilized by intermolecular C—H⋯O and C—H⋯Br and by intramolecular O—H⋯O hydrogen bonds.

6,6'-Dimethoxy-2,2'-[-4-bromo-o-phenylenebis (nitrilomethylidyne)]diphenol was synthesized according to modified reported methods (Xia, et al., 2007). A mixture of NiCl2.6H2O (1 mmol, 237.7 mg), 6,6'-Dimethoxy-2,2'-[-4-bromo-o-phenylenebis (nitrilomethylidyne)]diphenol (1 mmol, 455.3 mg) in 40 ml methanol and 20 ml water was refluxed for forty minutes. Crystals suitable for X-ray
were obtained by slow evaporation at room temperature for three weeks.All H atoms were placed in geometrically calculated positions with C—H = 0.96 Å for methyl H atoms, C—H = 0.93 Å for aromatic H atoms and were refined isotropic with Uiso(H) = 1.2Ueq(C) of parent atom using a riding model. H atoms of methanol were constrained to idealized geometries, with C—H = 0.96 Å for methyl H atoms, O—H = 0.82 Å, and with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O).

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. |

The synthesis and structural investigation of Schiff base complexes have attracted much attention due to their interesting structures and wide potential applications. They play an important role in the development of coordination chemistry as well as inorganic biochemistry, catalysis and optical materials (Aurangzeb et al., 1994; Fun & Kia, 2008; Hulme et al., 1997; Li et al., 2008; Fei & Fang, 2008; Zhang & Janiak, 2001). Here, the synthesis and crystal structure of the title complex (I) are reported.
The molecular structure of title compound is showing in Fig. 1. The dihedral angles between the aromatic ring planes of the middle aromatic ring and other two aromatic rings are 10.8 (3)° and 6.0 (2)°, respectively. The crystal structure, is stabilized by intermolecular C—H···O and C—H···Br and intramolecular O—H···O hydrogen bonds.
