Noncovalent Interactions of Heteroboranes

Popis výsledku v původním jazyce

This chapter deals with noncovalent interactions between heteroboranes and their various molecular partners. The physical essence of noncovalent interactions is first discussed in general. Subsequently, the bonding of boron clusters is discussed based ontheir unusual electron distribution, especially around the heteroatoms or the exo-substituents. The bare (i.e. not linked to hydrogen) heteroatoms within the cage bear prevailingly a partial positive charge. This results in an opposite direction of thecompound dipole moments (as proved experimentally), contrary to what would be expected from the electronegativity concept. The anisotropic distribution of the electron density around the heteroatoms gives rise to the so-called sigma-holes, regions of positive electrostatic potential (ESP). This can be viewed as a driving force for noncovalent interactions with, e.g. organic aromatics or Lewis bases. Examples of sigma-hole bonding of heteroboranes incorporated in the cluster cages are cha
