SPECTRAL STUDIES AND CHARACTERIZATION OF Cr(III) COMPLEXES WITH SOME NITROGEN-OXYGEN AND NITROGEN-SULPHUR DONOR LIGANDS

Cr(iii) complexes are synthesized with thiosemicarbazones (l^1, l^3 and l^5) and semicarbazones (l^2, l^4and l^6) derived from pyrrole-2-carboxyaldehyde, 2-acetyl furan and 2-acetyl thiophene. these arecharacterized by elemental analysis, molar conductance, magnetic susceptibility measurements, mass, ir,electronic and epr spectral studies. the molar conductance measurement of the complexes in dmsocorresponds to 1:1 electrolyte in nature. on the basis of spectral studies an octahedral geometry has beenassigned for all the complexes.
