Multinuclear magnetic resonance studies of the reactions of bidentate ligands with Pt(S2P{OEt}2)2. Crystal and molecular structure of (apeS)Pt(S2P{OEt}2)2 (ApeS = Ph2AsCH2CH2P(S)Ph2)

The interactions in dichloromethane solution of Pt(S2P{OEt}2)2 with a number of potentially bidentate ligands have been studied by multinuclear (31P, 77Se, 195Pt) magnetic resonance techniques. The ligands used (L-L′) were Ph2PCH2CH2PPh2 (dpe), Ph2AsCH2CH2PPh2 (ape), Ph2PCH2PPh2 (dpm), Ph2PCH2P(E)Ph2 (E = S, Se to give dpmS, dpmSe), and Ph2AsCH2CH2P(E)Ph2 (apeS, apeSe). All the ligands except apeS and apeSe react with Pt(S2P{OEt}2)2 in 1:1 proportions to give initially [(L-L′)Pt-(S2P{OEt}2)]+ and free [S2P(OEt)2]-, but a slower reaction gives (L-L′)Pt(S2P{O}OEt) and EtS2P(OEt)2 by attack of the free anion on the coordinated dithiophosphate ligand. In 1:2 proportions these ligands give [Pt(L-L′)2]2+ and free [S2P(OEt)2]-, except for dpm which gives [(η1-dpm)(η2-dpm)Pt(η1-S 2P{OEt}2)]+. The same products are obtained by reacting 1 mol of L-L′ with 1 mol of [(L-L′)Pt(S2P{OEt}2)]+, but the (L-L′)Pt(S2P{O}OEt) compounds do not react with further L-L′ ligand. The ligands apeE react with Pt(S2P{OEt}2)2 to give only (η1-apeE)Pt(η1-S2P{OEt} 2)(η2-S2P{OEt}2). The structures of all the complexes in solution were determined by multinuclear magnetic resonance studies and that of (η1-apeS)Pt(η1-S2P{OEt} 2)(η2-S2P{OEt}2) in the solid state was confirmed by a single-crystal X-ray diffraction study. Crystal data for (apeS)Pt(S2P{OEt}2)2: Mr = 1039.98, monoclinic space group P21, a = 10.107 (1) A?, b = 20.002 (2) A?, c = 11.278 (2) A?, β = 114.23 (2)°, Z = 2, ρmeasd = 1.65 (1) g cm-3, Mo Kα radiation, R = 0.030, Rw = 0.034 for 7695 independent reflections. The structure contains discrete molecules with the square-planar stereochemistry about platinum being defined by three sulfur atoms from one bidentate and one monodentate [S2P(OEt)2]- ligand and an arsenic atom from the monodentate apeS ligand.
