The title compounds were generated by the reaction between [Ptpp2Cl2, dppmE] and TlO3SCF3. On the basis of solution 31P, 77Se and 195Pt NMR spectroscopic data, a square-pyramidal structure is proposed with the chalcogen atom in the apical position. In contrast, [Pt(pp2-P,P′,P″)(dppmO-P)](O3SCF3)2 is four-coordinate. The reaction between Ptpp2Cl2 and dppmSe2 involves a selenium transfer yielding the cis and trans isomers of [PtPhP(CH2CH2PPh2)(CH2CH2P(Se)Ph2-P,P′)(dppmSe-P,Se)](O3SCF3)2, which are also accessible from [Pt(pp2-P,P′,P″)(dppmSe-P,Se)](O3SCF3)2 and elemental selenium.

Treatment of [Pt{PhP(CH2CH2PPh2)2}(PPh3)](O3SCF3)2 with NaBH4 gives the five-coordinate platinum hydride complex [PtH{PhP(CH2CH2PPh2)2}(PPh3)]+ or [PtH{PhP(CH2CH2PPh2)2})] depending on the reaction conditions. The zerovalent complex and the hydride are readily interconverted. The hydride complexes [PtH{PhP(CH2CH2PPh2)2}L]+, L = PBu3, PPh2H, PCy2H (Cy = cyclohexyl) and Ph2PCH2PPh2 have also been prepared.

Reactions of [Pt{PPh(CH2CH2PPh2)2}Cl]Cl or [Pt{P(CH2CH2PPh2)3}Cl]Cl with PR2H (R = Ph or C6H11) and Tl(O3SCF3) give secondary phosphine complexes [Pt{PPh(CH2CH2PPh2)2}(PR2H)][O3SCF3]2 or [Pt{P(CH2CH2PPh2)3}](PR2H)][O3SCF3]2. The corresponding terminal phosphido complexes were prepared by deprotonation with aqueous KOH or Na[N(SiMe3)2]. The new complexes were characterised by P-31 and Pt-195 n.m.r. spectroscopy. Phosphorus-31 n.m.r. spectra indicate that the geometry at the terminal phosphido phosphorus is pyramidal.

[Pt(pp3-P,P′,P″,P‴)H]O3SCF3 and [Pt(np3-N,P,P′,P″)H]O3SCF3 (pp3 = P[CH2CH2PPh2]3, np3 = N[CH2CH2PPh2]3) have been shown to react with phenylmercury hydroxide to give [PhHgPt(pp3-P,P′,P″,P‴)]O3SCF3 and [PhHg(np3-N,P,P′,P″)]O3SCF3, which have been characterized by 31P, 195Pt and 199Hg NMR spectroscopy.
