Boron

Journal article

Molecular wheels of eight- and nine-atom boron clusters have been observed by photoelectron spectroscopy and their structures confirmed by DFT calculations 1. The first cationic terminal borylene, containing a Fe=B double bond, [Cp*Fe(CO) 2-(Bmesityl)][BAr f4] has been synthesised. DFT calculations support a bonding model in which boron engages in π-bonding to both [Cp*Fe(CO) 2] + and mesityl moieties 2. The first thirteen vertex carborane has been prepared by successive reduction of 1,2-μ-{C 6H 4(CH 2) 2}-1,2-closo-C 2B 10H 10 with Na to afford the [7,8-μ-{C 6H 4(CH 2) 2}-7,8-nido-C 2B 10H 10] 2- ion followed by addition of PhBCl 2 to give the unprecedented 13-vertex carborane 1,2-μ-{C 6H 4(CH 2) 2}-3-Ph-1,2-C 2B 11H 10 which has a henicosahedral structure. 3.
