SYNTHESIS, CHARACTERIZATION AND PHYSICOCHEMICAL STUDIES OF Ni(II) AND Cu(II) COMPLEXES WITH SOME NITROGEN- OXYGEN AND NITROGEN SULPHUR DONOR LIGANDS
AbstractNi(II) and Cu(II) complexes of Schiff base thiosemicarbazones (L1) and semicarbazones (L2) derived from pyrrole-2-carboxaldehyde. These complexes are characterized by elemental analysis, molar conductance measurements, magnetic suscepectibility measurements, mass, IR, electronic and EPR spectral studies. The molar conductance measurements of the complexes in DMSO determine the non-electrolytes and electrolytes nature of the complexes based on their molar conductance value as higher value indicates the electrolytes nature of the complexes and lower value of the molar conductance indicates the non-electrolytes nature of the complexes. On the basis of spectral studies an octahedral geometry may be assigned for Ni(II) complexes except [Ni(L1)2](NO3)2 which are of tetrahedral geometry. A tetragonal geometry may be suggested for Cu(II) complexes.
