ABSTRACT
The title compound 1,1′-bis(diphenylphosphino)ferrocene dioxide has been analyzed by X-ray crystal diffraction analysis. The crystals are monoclinic, space group P2(1)/c with a = 22.461(5), b = 10.515(2), c = 12.024(2) Å, α = 90, β = 96.28(3), γ = 90°, V = 2822.7(10) Å3, Z = 4, F(000) = 1256, Dc = 1.422 g/cm3, μ = 0.683 mm−1, the final R = 0.0514 and wR = 0.1369. A total of 22218 reflections were collected, of which 4957 were independent (Rint = 0.0422). In the crystal packing diagram, intermolecular O‒H···O hydrogen bonds between the P=O and H2O stabilize the solid state of the title compound.
