A new P,S-coordinating ferrocenyl ligand: synthesis of a precursor and its coordination compounds with Pd^II and Pt^II

Fc(PSPh₂)(CH₂SPSPh₂), a new chiral ferrocenyl (Fc) compound, is the precursor to a new P,S-coordinating ferrocenyl ligand, [Fc(PPh₂)(CH₂S)]⁻, which reacts with Pd and Pt precursors giving dinuclear complexes displaying a butterfly geometry.
