Quick Summary

The term "conjuncto-borane" refers to a type of borane structure where two or more polyhedral borane clusters are joined together. Boranes are compounds of boron and hydrogen, and their structures are often complex polyhedrons. These structures can be classified using prefixes like closo (cage-like), nido (nest-like), and arachno (spiderweb-like), indicating the degree of openness of the boron atom arrangement.12

The bonding in boranes is unique, often involving multicenter bonding where three or more atoms share a pair of electrons. This makes them electron-deficient compounds. The simplest isolable borane is diborane (B₂H₆), which features three-center bridge bonding. Boranes have found applications in areas such as rocket fuels and as building blocks for advanced materials.13
