title: The bonding situation in triethylchalcogenostiboranes - polarized single bonds vs. double bonds.
abstract: Triethylchalcogenostiboranes Et3Sb[double bond, length as m-dash]E (E = S , Se ) were synthesized and their solid state structures were determined. The Sb-Se bond length is the shortest ever reported. Short SbE contacts were not observed. According to quantum chemical calculations, the bonding situation in and is best described as a polarized Sb-E single bond.
