Platinum hydride complexes. Effect of cis-ligands on J(Pt–H)

Abstract

The preparation of some new platinum hydride complexes [PtHL(AsEt₃)₂]ClO₄ is described. Some of these are obtained as mixtures of cis-and trans-isomers, and the effect of J(Pt–H) of changing a cis-ligand is found to be the reverse of the effect when the trans-ligand is changed. This is discussed in terms of current trans-influence theories. Preparations of some complexes trans-[PtXL(AsEt₃)₂]ClO₄(L = CO, Me₃CNC, or AsEt₃; X = Cl or Br) are also reported.
