Sulfur dioxide model structure

The amphoteric nature of the nitrosyl ligand has been extensively discussed by several authors in terms of molecular orbital models and in particular the utility of the extended Hiickel approach for understanding the bonding has been demonstrated by Hoffmann, et al. This latter work has been extended to sulfur dioxide complexes by Ryan and Eller The interested reader is referred to the recent review by Mingos for a summary Although detailed molecular orbital treatment will no doubt be necessary for a complete understanding of SO2 bonding, we find that the simple acid/base concept serves to correlate the presently known structural information. This point of view will be emphasized in the present article and extended to include >7 -802 as a r acid 1...
