The interaction of FeCl 3 with PPh 3 in chloroform. X-ray crystal structure of [Ph 3PCH 2PPh 3][FeCl 4] 2

Abstract

Interaction of FeCl 3, and PPh 3 in CHCl 3 yields complex mixtures containing unstable adducts. The compound [Ph 3PCH 2PPh 3][FeCl 4] 2·CHCl 3 was isolated from the solution after the decomposed mixture had been allowed to interact with air. Crystal data: triclinic, space group P1̄, a = 11.459(4), b = 12.102(2), c = 18.109(4) Å, α = 105.15(2), β = 102.14(2), γ = 94.91(2)°, V = 2347(2) Å 3, Z = 2, d c = 1.49 g cm −3, μ(Mo- K α) = 13.49 cm −1, R = 0.045 ( R w = 0.054) for 487 parameters and 5256 observed reflections with F 0 2 > 3 σ ( F o 2).
