| Abstract: | The Raman and IR spectra of LnTPPTS·10H2O Ln=La,Sm, TPPTS=P(m-C6H4SO3)

] complexes are reported. Based on the observed Raman and IR characteristic frequencies, a vibrational assignments has been
made for these complexes. Coordination induces a lengthening of the S−O bonds and a shortening of the C−S bond. The C−S stretching
frequencies should therefore increase while the position of the
should move to a lower wavenumber. Vibrational modes of metal-oxygen polyhedron V
(La-O) at 146, 168,253 cm−1 are the structural charactrization for coordinate bond of LnTPPTS complexes.
