Abstract
The ligand,
1-phenyl-2,3-dimethyl-4-isovalerylpyrazol-5-one, here denoted with (ipy) and
its complexes of praseodymium (III) and dysprosium (III) were synthesized and
characterized spectroscopically using infra red (IR). Percentage yield was
determined for the complexes synthesized. Physical properties including colour,
melting points and conductivity measurements were also investigated. Pr (III)
and Dy (III) reacted with the ligand in the metal-ligand mole ratios of 1:3 to
form neutral complexes of diaquo-trischelate Pr(ipy)3.2H2O
and, Dy(ipy)3.2H2O respectively, giving coordination
number of eight for both complexes.
