Structural investigations of ylides. Part III. Crystal and molecular structure of N-(dimethylsulphonio)toluene-p-sulphonamidate
Abstract
The crystal and molecular structure of the title compound has been determined from X-ray photographic data. Crystals are monoclinic, space group P21/c, with Z= 4 in a unit cell of dimensions a= 12·93(2), b= 7·17(1), c= 12·50(2)Å, β= 104·2(1)°. The structure was solved by the heavy atom technique and refined by least-squares calculations to R 0·107 for 1085 independent data. The molecular geometry is compared with those of other similar ylides in relation to the possibility of d-orbital involvement within the S–N–S bonding system.
