A new method for preparing Bi2Ph4 consists of reducing BiPh2I with bis(cyclopentadienyl)cobalt(II) in tetrahydrofuran as solvent, with yields as high as 80%. The mixed products Ph2BiEPh (E = S, Se, Te) were obtained by reacting Bi2Ph4 with E2Ph2 in toluene as solvent at room temperature. The crystal and molecular structure of BiSePh3 has been solved. Crystal data: C18H15BiSe, Mr = 519.3, orthorhombic, space group P212121, a = 15.936 (3) ?, b = 11.550 (3) ?, c = 8.855 (2) ?, Z = 4, d(calcd) = 2.116 g cm-3. The structure consists of tricoordinated and bicoordinated bismuth and selenium, respectively, paired by a Bi-Se bond 2.704 (3) ? long. The tellurium and selenium mixed species undergo diazomethane insertion with formation of the Ph2Bi-CH2-EPh species. Tetraphenyldibismuthine is oxidized by elemental selenium, giving (BiPh2)2Se.
