摘要: Tetraethyldibismuthine (Bi2Et4) reacts with elemental chalcogens insertion into the Bi–Bi bond and formation of bis(diethylbismuthanyl)chalcogenanes ((Et2Bi)2E; E = S (1), Se (2), Te (3)). The structures 1–3 were determined by single crystal X-ray diffraction. complexes exclusively adopt syn-anti conformations in solid state. molecules show weak intermolecular Bi···chalcogen contacts, resulting a three-dimensional network corner-shared Bi4E tetrahedra (E S, Se, Te).
