Several unstable [Pt(L–L)l4] complexes have been prepared, which lose iodine very easily and are partially dissociated in solution. Chlorine oxidation of [Pt(L′–L′)2Cl2][L′–L′=o-C6H4(AsMe2)2, Me2PCH2CH2PMe2, or o-C6H4(PMe2)(AsMe2)] produced trans-[Pt(L′–L′)2Cl2]Cl2, but for L′–L′=o-C6H4(AsPh2)2 or cis-Ph2AsCHCHAsPh2 the product was [Pt(L′–L′)Cl4] and oxidised ligand. The complex [Pt(Ph2PCH2CH2PPh2)2Cl2]
