ABSTRACT
Ni (II) and Cu (II) complexes were synthesized with L1(Pyridine-2-carboxaldehydethiosemicarbazones) and L2 (Pyridine-2-carboxaldehydesemicarbazones). These complexes were characterized by elemental analysis, molar conductance measurements, magnetic susceptibility measurements, mass, IR, electronic and EPR spectral studies. The molar conductance measurements on the complexes in DMSO correspond to non electrolytes nature with L1. The molar conductance measurements with L2 lie in the range 210-226 Ω-1cm2mol-1 indicating the complexes were 12 electrolyte thus the complexes may be formulated as [M(L)2]X2 where M= Ni (II) and Cu (II) complexes. On the basis of spectral studies an octahedral geometry has been assigned for Ni (II) complexes. A tetragonal geometry suggested for Cu (II) complexes.
