Abstract

Abstract: The preparation and properties of anionic 10-S-5, 104-4, and 10-S-3 species (1, 2, and 3) are described. The X-ray crystallographic structures show these species to be pseudotrigonal bipyramidal in geometry in the solid state. Data from pKa measurements and low-temperature NMR spectra prove the importance of hypervalent bonding in the ground- state structures in solution as well. The anions of 1 and 2 are the first examples of ...
