Abstract

In the title compound, [CrCl₃(C₁₉H₁₃Br₂N₃)], the Cr³⁺ion is coordinated by the tridentate 2,6-bis[(4-bromophenyl)iminomethyl]pyridine Schiff base ligand in a fac-octahedral geometry. The dihedral angles between the pyridine and benzene rings are 23.9 (6) and 70.7 (1)°.

Comment

Schiff bases have often been used as chelating ligands in coordination chemistry (Yin et al. (2010); Yang et al. (2010); Rohini et al. (2009): Legrand et al. (2009)). We report here the crystal structure of the title new chromium complex with the chelating Schiff base ligand 2, 6-bis [1-(4-bromophenylimino)] pyridine The Cr atom in the complex is six-coordinated by one pyridine N and two imine N atoms of the Schiff base ligand, and by two bromide atoms, forming tetrahedral geometry (Fig.1). The dihedral angle between the pyridine and the benzene rings is 23.9 (6) ° and 70.7 (1) °. The bond lengths (Table 1) related to the Cr atom are comparable to those observed in similar chromium complexes (Sugiyama et al. (2002); Sun et al. (2009); Gong et al. (2009); Xiao et al. (2010)).

Experimental

2,6-bis[1-(4-bromophenylimino)]pyridine(0.0226 g, 0.05 mmol), and CrCl₃?6H₂O (0.0139 g, 0.05 mmol) were mixed and stirred in ethanol(10 ml) for 2 min and then heated in a stainless steel reactor with Teflon liner at 353 K for 72 h. After cooling at 5 K per hour, green crystals were obtained.

Special details

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.
