By electrochemical oxidation of (n-Bu4N)2[B9H9] in the presence of nitrite ions and the base DBU in dichloromethane solution [1-(NO2)B9H8]2- is formed. X-ray diffraction analysis has been performed on a single crystal of (Ph4P)2[1-(NO2)B9H8] · CH3CN (monoclinic, space group P21 a = 10.643(5), b = 32.661(5), c = 13.924(5) Å, β = 96.68°, Z = 4). By reduction of [1-(NO2)B9H8]2- with FeSO4 in aqueous alkaline solution the amino derivative [1-(NH2)B9H8]2- is formed. The UB NMR spectra of both compounds are consistent with a monosubstituted tricapped trigonal prism. The IR and Raman spectra exhibit characteristic BB, BH, NO and NH vibrations, respectively.
