Polarization Upends Convention: Halogen Bonding Propensities of Main Group Halides.

ABSTRACT: The propensities for sigma hole bonding by halogen atoms bonded to central atoms below period 2 in the periodic table remain to be systematically examined. Using iodine as our reference halogen atom, a comprehensive analysis of the tendencies for halogen and other forms of significant sigma hole bonding by simple compounds of main group atoms from H to At is accomplished. An examination of the structure and bonding of complexes formed by those iodine-substituted main group compounds and sigma donating bases (ammonia and trimethylamine) is performed to probe the viability of halogen bonding by heavy main group R_nM-I compounds in particular, given the historic focus on period 2. We show that propensities for halogen bonding by F_nM-I systems for certain col
