The interactions in dichloromethane solution of Pt(S/sub 2/P(OEt)/sub 2/)/sub 2/ (I) with a number of potentially bidentate ligands have been studied by multinuclear (/sup 31/P, /sup 77/Se, /sup 195/Pt) magnetic resonance techniques. The ligands used (L-L') were Ph/sub 2/PCH/sub 2/CH/sub 2/PPh/sub 2/ (dpe), Ph/sub 2/AsCH/sub 2/CH/sub 2/PPh/sub 2/ (ape), Ph/sub 2/PCH/sub 2/PPh/sub 2/ (dpm), Ph/sub 2/PCH/sub 2/P(E)Ph/sub 2/ (E = S, Se to give dpmS, dpmSe), and Ph/sub 2/PCH/sub 2/CH/sub 2/P(E)Ph/sub 2/ (apeS, apeSe). All the ligands except apeS and apeSe react with (I) in 1:1 proportions to give initially ((L-L')Pt(S/sub 2/P(OEt)/sub 2/))/sup +/ and free (S/sub 2/P(OEt)/sub 2/)/sup /minus//, but a slower reaction gives (L-L')Pt(S/sub 2/P(O)OEt) and EtS/sub 2/P(OEt)/sub 2/ by attack of the free anion on the coordinated dithiophosphate ligand. In 1:2 proportions these ligands give (Pt(L-L')/sub 2/)/sup 2+/ and free (S/sub 2/P(OEt)/sub 2/)/sup /minus//, except for dpm which gives ((/eta//sup 1/-dpm)(/eta//sup 2/-dpm)Pt(/eta//sup 1/-S/sub 2/P(OEt)/sub 2/))/sup +/. The same products are obtained by reacting 1 mol of L-L' with 1 mol of ((L-L')Pt(S/sub 2/P(OEt)/sub 2/))/sup +/, but the (L-L')Pt(S/sub 2/P(O)OEt) compounds do not react with further L-L' ligand. The ligands apeE react with to give only (/eta//sup 1/-apeE)Pt(/eta//sup 1/-S/sub 2/P(OEt)/sub 2/)(/eta//sup 2/-S/sub 2/P(OEt)/sub 2/). The structures of all the complexes in solution were determined by multinuclear magnetic resonance studies and that of (/eta//sup 1/-apeS)Pt(/eta//sup 1/-S/sub 2/P(OEt)/sub 2/)(/eta//sup 2/-S/sub 2/P(OEt)/sub 2/) in the solid state was confirmed by a single-crystal x-ray diffraction study. 21 references, 4 figures, 8 tables.
