What is Structure and solution behaviour of cyclooctadiene complexes of platinum(II) about?
The substitution behaviour of [PtCl(R)(COD)] (R À = Me and Fc) complexes, by the stepwise addition of phosphine ligands, L (L = PPh 3 , PEt 3 and P(NMe 2 ) 3 ), were investigated in situ by 1 H and 31 P NMR spectroscopy. Addition of less than two equivalents of the phosphine ligand results in the formation of dimeric molecules with the general formula trans-[Pt(R)(l-Cl)(L)] 2 for the sterically demanding systems where R À = Me/L = P(NMe 2 ) 3 and R À = Fc/L = PEt 3 , PPh 3 and P(NMe 2 ) 3 while larger quantities resulted in cis-and trans mixtures of mononuclear complexes being formed. In the case of the relatively small steric demanding, strongly coordinating, PEt 3 ligand the trans-[PtCl(R)(PEt 3 ) 2 ] mononuclear complexes were exclusively observed in both cases. The crystal structures of the two substrates, [PtCl(R)(COD)] (R À = Me or Fc), as well as the cis-[PtCl(Fc)(PPh 3 ) 2 ] substitution product are reported.
