Syntheses and Solid‐State Structures of Bis(dialkylstibanyl)sulfanes and ‐telluranes

Abstract

Abstract Distibines Sb 2 R 4 (R = Me, Et) react with elemental chalcogens (E = S, Se, Te) with insertion into the Sb–Sb bond and formation of the corresponding bis(dialkylstibanyl)sulfanes, ‐selenanes, and ‐telluranes (R 2 Sb) 2 E. The structures of (Et 2 Sb) 2 S ( 1 ), (Et 2 Sb) 2 Te ( 3 ), and (Me 2 Sb) 2 Te ( 4 ) were determined by single‐crystal X‐ray diffraction. The complexes either adopt a syn – syn ( 1 , 4 ) or syn – anti conformation ( 3 ) in the solid state. In addition, the compounds have different intermolecular interaction modes, which depend on the bridging chalcogen and the organic substituent bound to the Sb atoms.
