✦ Synopsis
The Bis[N-(diphenylphosphanylselenoyl)-P,P-diphenylphos-spectrometry and elemental analysis. The molecular structure was determined using single-crystal X-ray phanylselenoic amidato-Se,SeЈ]selenium(II) (1) was prepared by treating [K{N(SePPh 2 ) 2 }] with [Se{S 2 P(O-iPr) 2 } 2 ] in THF. diffraction. The Se(Se 4 ) core exhibited a quasi perfect square planar geometry. Two selenide ligands are coordinated The title compound was characterized by means of IR and 31 P-NMR spectroscopy and positive-ion FAB mass symmetrically to the central atom forming a spiro complex.
