Some tertiary arsine complexes of platinum and palladium

Abstract

A series of square-planar complexes of platinum and palladium of the general formula MX₂L₂, where M is Pt or Pd, X is Cl, Br or I, and L is EtPh₂As or PrPh₂As, have been made. The platinum complexes (X = Cl or Br) react with the corresponding halogens to give octahedral complexes of the type PtX₄L₂. The dichloro complexes of platinum(II) react with carbon monoxide to give carbonyl complexes of the type trans- [PtCl(CO)L₂]⁺. Structures have been assigned to all the compounds.
