By electrochemical oxidation of (n-Bu4N)[B6H6(CH3)] in the presence of nitrite ions and of the base DBU in dichloromethane solution cis- and trans-[B6H4(CH3)(NO2)]2- , fac- [B6H3(CH3)(NO2)2]2- and mer-[B6H3(CH3)(NO2)c2]2- are formed. X-ray diffraction analyses have been performed on single crystals of cis-(Ph4As)2[B6H4(CH3O)(NO2)] (1) (monoclinic, space group P21/a, a = 20.063(2), b = 10.858(1), c =21.384(2) Å, β = 105.818(9)°, Z = 4), fac-(Ph4As)2[B6H3(CH3)(NO2)2] ·CH3CN (2) (triclinic, space group P1̄, a = 10.333(3), b = 10.695(3), c = 22.833(6) Å, α = 93.91(3), β = 96.79(3), γ = 104.56(2)°, Z = 2), and mer-(Ph4P)2[B6H3(CH3)(NO2)c2] (3) (triclinic, space group P1̄, a - 10.100(1), b = 10.402(3), c = 22.923(3) Å, α = 96.328(18), β = 89.928(12), γ = 107.963(16)°, Z = 2). The 11B NMR spectra and the vibrational spectra of the methylnitro compounds are discussed and compared with those of the monomethyl- and mononitro-closo-hexaborates.
