d.gif">C,N,C 12-electron donor. From 1 more soluble dinuclear [Pt2(L)(L')2](L' = bulky 2-electron donors such as PR3 and substituted pyridines) species, 2-6, and polynuclear{Pt2(L)(L-L)}n (L-L = Ph2P(CH2)xPPh2 (x = 1, dppm; x = 2, dppe; x = 3, dppp)) species, 7-9, havebeen obtained by substitution of the DMSO ligands. DMSO can also be displaced from 1 by CO, bothin solution and in the solid state, to give the flat and completely insoluble complex [Pt2(L)(CO)2] (10).The structures of [Pt2(L)(3,5-Me2-Py)2] (5) and {Pt2(L)(dppe)}2 (8) have been determined by single-crystal X-ray diffraction analysis, while a powder X-ray diffraction analysis has been performed on complex10, [Pt2(L)(CO)2]. With a 1:1 Pt:L molar ratio a mononuclear complex, [Pt(H2L)(DMSO)] (11), is obtained,where the twofold deprotonated ligand is C,N,C coordinated. Also, the DMSO can be displaced from 11by neutral ligands, L', such as CO, PPh3, and 3,5-Me2-py to give [Pt(H2L)(L')] (12-14). Compounds11-14 further react with cis-[Pt(R)2(DMSO)2] to give dinuclear complexes. This two-step approach allowsus to obtain species with different ligands around each platinum atom, [Pt2(L)(L')(L' ')] (15-18).
