The dodecaborate(12) anion, [B 12 H 12] 2−, is a borane with an icosahedral arrangement of 12 boron atoms, with each boron atom being attached to a hydrogen atom. Its symmetry is classified by the molecular point group I h .
Caesium dodecaborate is an inorganic compound with the formula Cs 2 B 12 H 12. It is a salt composed of caesium and dodecaborate(12) ions. The [B 12 H 12 ] 2− anion has been of great theoretical interest to the chemistry community.
Boron is renowned for cluster species, e.g. dodecaborate [B 12 H 12] 2-. Such clusters have many organic derivatives. One example is [B 12 (CH 3) 12] 2-and its radical derivative [B 12 (CH 3) 12] −. [16] Related cluster compounds with carbon vertices are carboranes; the best known is orthocarborane, C 2 B 10 H 12. Carboranes have few ...
From the structural perspective, the most distinctive chemical compounds of boron are the hydrides. Included in this series are the cluster compounds dodecaborate (B 12 H 2− 12), decaborane (B 10 H 14), and the carboranes such as C 2 B 10 H 12. Characteristically such compounds contain boron with coordination numbers greater than four. [1]
The dodecaborate anion ([B 12 H 12] 2−) was discovered by Pitochelli and Hawthorne. Hawthorne's contributions focused on the chemistry of boron hydride clusters. He discovered dodecaborate anion (B 12 H 12 2−) [3] and metal complexes of the dicarbollide anion. [4] His group subsequently discovered the perhydroxylation of B 12 H 12 2−. [5]
The development of the borane hydride clusters resulted from pioneering work by Alfred Stock, invented the glass vacuum line for their study. [2] The structures of the boron hydride clusters were determined beginning in 1948 with the characterization of decaborane.
Despite the low reactivity of the tetrafluoroborate anion in general, BF − 4 serves as a fluorine source to deliver an equivalent of fluoride. [2] The Balz–Schiemann reaction for the synthesis of aryl fluorides is the best known example of such a reaction. [3]
