An unpaired electron incarcerated within an icosahedral borane cage: synthesis and crystal structure of the blue, air-stable {[closo-B12(CH3)12]·}– radical
Abstract
Oxidation of the permethylated icosahedral borane [closo-B12(CH3)12]2– 1, by ceric(IV) ammonium nitrate in acetonitrile affords the blue, air-stable paramagnetic anion {[closo-B12(CH3)12]·}– 2, which has been characterized, among other means, by X-ray crystallography.
