Abstract

I-X (X=O, N, C) bonding was analyzed in the related hypervalent iodine compounds based on the adaptive natural density partitioning (AdNDP) approach. The results confirm the presence of a I→X σ dative bond, as opposed to the widely used I=X notation. A clear formulation of the electronic structure of these hypervalent iodine compounds would be useful in establishing reaction mechanisms and electronic structures in bioinorganic problems of general applicability. Singled out: The nature of the I-X (X=O, N, C) chemical bonding was examined and compared amongst different hypervalent iodine molecules. The common I=X representation is questioned by results of chemical bonding analyses which confirm the presence of I→O, I→N, and I→C single dative bonds in such compounds.
