The mononuclear chelate complexes (X = CF3CO2 or Cl; R = Me, Et, or Prⁱ) have been prepared and characterized spectroscopically.Reaction of with Prⁱ2PCH2PHPrⁱ gave a novel binuclear complex, iPCH2PPrⁱ2)(μ-Prⁱ2PCH2PHPrⁱ)>, with the phosphidophosphine ligand in an unusual bridging mode.This complex was characterized by 1H and 31P n.m.r. spectroscopy and by X-ray crystal-structure analysis of its trichloromethane solvate , a = 8.744(2), b = 11.483(1), c = 20.108(4) Angstroem, α = 103.49(1), β = 97.15(2), γ = 91.11(2) deg, Z = 2, R = 0.035 for 5 918 symmetry-independent reflections with I >/= 3?(I)>.
