Reaction of [2(μ,η2-P2)] (1) with LiBEt3H in THF at −78 °C affords the new phosphanido complexes [2(μ-PH2)(μ-H)] (2), [2(μ-PH2)2] (3), and [2(μ-PH)] (4), which have been characterized by single-crystal X-ray diffraction methods. The structure of 4 reveals a triple-decker sandwich complex with a distorted cyclo-P5 middle deck. The EPR spectrum of the paramagnetic (S‘ = 1/2) complex 4 (T = 130 K) is interpreted with a rhombic-symmetric spin Hamiltonian. A noticeable hyperfine interaction with two 31P nuclei is observed.
