Synthesis, characterization and crystal structure of octahedral

Preparation of two Schiff bases via efficient condensation of ? –bromocinnamaldehyde and thiosemicarbazide or bis(4-aminophenyl) ether is described in high yield at 100 0C, methanol solvent and neutral PH. The elemental analyses, FT-IR, 1H NMR and 13C NMR spectroscopy are agreed with two new Schiff bases structure. The complex [Co(5,5?-dmbpy)3]Cl3.CH3CN.2H2O(1) where 5,5?-dmbpy = 5,5?-dimethyl-2,2?-bipyridine was synthesized and characterized by the elemental analysis, IR, UV–Vis, CV, 1H-NMR and 13C-NMR spectroscopies and the single crystal X-ray diffraction method. The X-ray diffraction study of compound 1 indicated the Co(III) ion is six- coordinated in distorted octahedral configuration. The crystal data for [Co(5,5?-dmbpy)3]Cl3.CH3CN.2H2O at 25?C are as follows: monoclinic, space group P21/n with a = 13.5684(9) ?, b = 14.4082(9) ?, c=19.4228(13) ?, B = 92.210(5)? and Z = 4.
