Synthesis and Characterization of New Trinuclear Palladium(II) and Platinum(II) Complexes Containing Phosphorus-Sulphur Ligands

Abstract

Some new homo and hetero trinuclear Pd(II) and Pt(II) complexes
with tridentate hybrid ligands containing phosphorus-sulphur
species, of the general formula [M_nM_3-n  L₂CI₆], where
M = M' = Pt or Pd, n = 3; M = Pt, M' = Pd, n = 1 or 2 and L = cis-
1,2-bis(diphenylphosphino) phenylthioethylene (L¹) or cis-1,2-bis
(diphenylphosphino)-2-aminophenylthio ethylene (L²), have been
synthesized and characterized physico-chemically and spectroscopically.
The structures of the complexes have been elucidated on the
basis of their elemental analyses, electronic and infrared spectral
measurements.
