In the reaction of [B6H6]2- with diiodopentane or diiodohexane in dichloromethane μ-pentamethylene-bis-hexahydro-closo-hexaborate, [B6H6(CH2)5B6H6]2- (I), and μ-hexamethylene-bishexahydro-closo-hexaborate, [B6H6(CH2)6B6H6]2- (II), are formed, respectively. The products were separated from excess [B6H6]2- by ion exchange chromatography on diethylaminoethyl cellulose and have been identified and characterized by 11B, 13C, 1H NMR and vibrational spectroscopy.
