derivatives [PtCl 2O= NCMe 2C(R)= NOH}] (R = Me 16; Ph 17), respectively, while the corresponding chlorination of the bis-chelates [PtHO(H) NCMe 2C(R)= NOH} 2] (R = Me 10; Ph 11) gives [PtO= NCMe 2C(R)= NO} 2] (R = Me 18; Ph 19). The formulation of 5- 19 is based on C, H, and N microanalyses, IR, 1D ( (1)H, (13)C (1)H}, (195)Pt) and 2D ( (1)H, (1)H-COSY, (1)H, (13)C-HSQC) NMR spectroscopies, and X-ray diffraction

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]
