Summary
A series of new five-coordinate complexes of cobalt(II) of the type, dihalotris-(2-substituted imidazole)cobalt(II), of formulae Co(2-MeIm)3Cl2, Co(2-EtIm)3X2 (X = Cl, Br, I) and Co(2-i-PrIm)3I2, were synthesized and characterized by elemental analyses, electrolytic conductivity, diffuse reflectance as well as by solution spectra, i.r. and far i.r. spectra, x-ray powder pattern and magnetic susceptibility measurements. The mass spectra of the complexes did not exhibit peaks due to the molecular ions, but only showed the ligand fragmentation patterns. The t.g.a. and d.t.a. measurements were also carried out for the complexes.
