Characteristic variations in the bond angles and bond lengths

Abstract

In this section the geometrical parameters determined for the sulphur bond configurations in the sulphone molecules are compared, characteristic tendencies in their changes are pointed out, and explanations are sought employing considerations on valence shell electron pair repulsions and on non-bonded (atom-atom) interactions. The role of electron pair repulsions is examined for the changes in various series of parameters referring to molecules which differ from each other in the ligands (and their electronegativity) attached to the SO₂ group. The variations of non-bond distances are inspected in order to judge the possible importance of non-bonded interactions.
