By electrochemical oxidation of (n-Bu4N)[B6H5Hfac(CH2Ph)] in the presence of nitrite ions in dichloromethane solution cis-[B6H4(CH2Ph)(N O2)]2- is formed. X-ray diffraction analysis has been performed on a single crystal of cis-(Ph4P)2[B6H4(CH2Ph)(NO2)] HO2CH3CN (triclinic, space group Pl̅ a = 11.338(5), b = 11.377(5), c = 21.081 (5) Å, α = 93.727(5), ß = 98.872(5), γ = 105.926(5)°, Z = 2). The 11B NMR spectrum is consistent with a disubstituted octahedral B6 cage with local C2v symmetry. The IR and Raman spectra exhibit characteristic CH, NO2, BN, BH and B6 vibrations.
