Crystal and Molecular Structure.

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