Two novel diaryl (alkoxy)(acyloxy) spiro-λ4-sulfanes (3 and 5) exhibiting isomerism in relation to swapping of the five-and six-membered spiro-rings and two analogous cyclic alkoxysulfonium salts (4 and 6) with intramolecular S··· O interaction have been prepared and their molecular structures determined by X-ray diffraction. In all cases the arrangement of the ligands about the central sulfur atom shows a slightly distorted trigonal bipyramidal ( ...
