The Pd0 three-coordinate (np3)Pd, [np3= N(CH2CH2PPh2)3], and the Pt0 pseudotetrahedral (np3)Pt(PPh3) complexes react with R2AsX (R = Me, X = I; R = Ph, X = Cl) and NaBPh4 to give [(np3)MAsR2]BPh4, the first examples of terminal arsenides of platinum metals; the molecularstructure of [N(CH2CH2PPh2)3]PtAsPh2}BPh4 has been established by single-crystal diffraction methods.

The platinum(0) complex (np3)Pt(PPh3) (np3 = N(CH2CH2PPh2)3), undergoes oxidative addition by ClPEt2, in the presence of NaBPh4, to yield the five-coordinate terminal phosphide [(np3)Pt(PEt2)](BPh4). When the solvated compound (np3)Pt(PPh3).0.4CH3CH2CH2CH2OH is used as starting material, [(np3)Pt(PHEt2)](BPh4)2 is formed by reaction of the phosphide with HCl released by alcoholysis of ClPEt2. The related complex [(pp3)Pt(PEt2)](BPh4) (pp3 = P(CH2CH2PPh2)3}) has been prepared by deprotonation of [(pp3)Pt(PHEt2)](BPh4)2, for comparison purposes. The complexes have been characterized by elemental analyses, conductibility measurements and H-1 and P-31 NMR spectra. The X-ray structural analysis of [(np3)Pt(PHEt2)](BPh4)2 has been carried out.
