Electron-deficient borane and carbaborane clusters
In this section, we introduce electron-deficient clusters containing boron, focusing on the small clusters [B6H6]2-, B5H9 and B4H10. A comprehensive treatment of borane and carbaborane clusters is beyond the scope of this book, but more detailed accounts can be found in the references cited at the end of the chapter. An electron-deficient species possesses fewer valence electrons than are required for a localized bonding scheme. In a cluster, the atoms form a cage-like structure.
