Compounds containing unpaired electrons can be used as the starting material for the preparation of
molecular magnetic materials and other paramagnetic organometallic complexes.
We have synthesized various types of paramagnetic lanthanide
                         R
complexes [P(CH2NC6H3 )3]Ln(THF)3 {(R = H3, 3,5-(Me)2, 3,5-
(CF3)2) (Ln = Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm & Yb)} by
using tripodal amido ligands that were developed in our lab. In
these 6-coordinated metal complexes, three THF molecules and
three nitrogen atoms of amido ligands are attached with metal
center. These complexes were further characterized by their
NMR spectra, molecular structures and elemental analysis.
Magnetic studies of these complexes at various temperatures
(1.8 – 300K) were performed by SQUID magnetometer and
unusual magnetic behavior of thullium compounds was
observed. These compounds were further used for the study of heterobimetallic complexes.
