The IX (X=O,N,C) Double Bond in Hypervalent Iodine Compounds: Is it Real?

Angewandte Chemie International Edition by Alexander S. Ivanov, Ivan A. Popov, Alexander I. Boldyrev, Viktor V. Zhdankin  /  4d  //  keep unread  //  hide  //  preview Abstract IX (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 IX σ dative bond, as opposed to the widely used IX 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 IX (X=O, N, C) chemical bonding was examined and compared amongst different hypervalent iodine molecules. The common IX representation is questioned by results of chemical bonding analyses which confirm the presence of IO, IN, and IC single dative bonds in such compounds. Visit Website
