Synthesis, Reactivity, and Crystal and Molecular Structure of Tetraphenyldibismuth, Bi2Ph4

Tetraphenyldibismuth, Bi2Ph4, is best prepared by the reaction of BiPh2I with 1 equivalent of sodium in liquid ammonia, followed by extraction with toluene and recrystallization from anhydrous ethanol.It is sensitive to air and slightly thermocromic.The crystal and molecular structure was solved by X-ray diffraction methods: triclinic, space group , with a=7.865(4), b=11.444(5) c=6.257(3) Angstroem, α=105.24(4), β=94.20(7), γ=96.52(6) deg, and Z=1; R=0.0560 for 1 097 absorption-corrected reflections having I>=3?(I).The molecule has a staggered trans conformation, with bismuth-bismuth distance of 2.990(2) Angstroem.Tetraphenyldibismuth reacts promptly with di-iodine to give BiPh2I, and with p-benzoquinne, elemental sulphur, and diazomethane to give the corresponding products of bismuth(III) resulting from oxidative insertion into the bismuth-bismuth bond.
