Platinum(II) complexes of cyclic triphosphenium ions: A 31P NMR spectroscopic and computational study

The first transition metal complexes of cyclic triphosphenium ions have been unequivocally identified in solution by 31P NMR spectroscopy. The ligands coordinate to platinum(II) via the central phosphorus atom, but only when at least one of the outer phosphorus atoms has non-aromatic substituents. Depending on the system, either trans- (the kinetic reaction product) and/or cis- (the thermodynamic reaction product) complexes are formed. The 1J coupling constants between 195Pt and the central phosphorus atom of the CTI (PA) are small for both cis- and trans-isomers, between 900 and 1300 Hz, whereas other phosphanes in these complexes derived from the platinum(II) starting material show normal 1JPtP values. These results suggest a possible long P-Pt bond between the overall positively charged ligand and the platinum(II) cation. Calculations including predicted 31P NMR shifts for the CTIs and their Pt(II) complexes largely support our experimental findings.

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.
