Reaction of [PdCl ₂ (PPh ₃) ₂] with imidazolidine-2-thione {SC₃H₄ (NH) ₂} in the presence of triethylamineinvolved activation of N–H bonds and formed an unusual oxo-bridged dianion, (SC ₃H ₄N ₄–O–N ₂C ₃H ₄S) ² ⁻ coordinated to PdII in [Pd{κ ³–S, O,S–(SC ₃H ₄N ₂–O–N ₂C ₃H ₄S)}(PPh₃)]•CH₃CN 1, which hasbeen studied using elemental analysis, IR, NMR, X-ray crystallography and ESI-mass studies.
