Abstract
Some complexes of the type CoX3(L) (X = Cl, Br, I) and CoX2Y(L) (X = Cl Br; Y = Br I; X ≠ Y; L = monoprotonated 1-methyl and 2-methyl-piperazine) were prepared and investigated by means of magnetic and spectroscopic measurements. All the magnetic and spectroscopic results indicate that CoX3(L) complexes possess a pseudotetrahedral C3ν symmetry and the CoX2Y(L) complexes a Cs symmetry. On the basis of these symmetries the bands of their electronic spectra are assigned.Particular attention is paid in this work to the far-infrared spectra and the Co-X, Co-Y and Co-N vibrations of all the complexes are -assigned with a reasonable certainty.
