Abstract:
Cu(II),
Ni(II), and Co(II) complexes are synthesized with 2-acetyl
pyridine semicarbazone. These Complexes are characterized by
elemental analysis, molar conductance, magnetic susceptibility
measurement, mass, IR, electronic & EPR spectral studies. The
molar conductance measurement of the complexes in DMSO indicates
that the complexes are non-electrolyte except [Co(L)2(NO3)2]
and [Ni(L)2(NO3)2] complexes.
All complexes are of high-spin type. On the basis of spectral
studies an octahedral geometry may be assigned for Co(II), &
Ni(II) complexes except [Co(L)2(NO3)2]
and [Ni(L)2(NO3)2] , which are
tetrahedral whereas tetragonal for Cu(II) complexes. On the
basis of molar conductance the complexes may be formulated as
[M(L)2X2], M = , Ni2+, Co2+,
Cu2+, X = Cl-, NO3- and [M(L)2]X2
, [M= , Ni2+, Co2+, X= NO3-].
Key words: 2- acetyl pyridine, semicarbazone , transition metal
