Crystal and Molecular Structure.

Abstract

The history of the early chemical and structural studies of boranes is referred to briefly with emphasis on the geometrical differences between compounds of carbon, and the more compact compounds of boron. The second part discusses the nature of three-center bonds, and their use in explaining the bonding in some of the more open types of boron compounds. In the third part molecular orbitals are described, with special reference to their transferability among geometrically related systems. The use of molecular orbital methods for prediction is exemplified. Finally the value of all of these methods is tested for predictions of chemical reactivity and molecular transformations with emphasis on boranes and carboranes.
