Abstract

Abstract By reduction of [B6Cl5(p-C6H4 (NO2))]2- with hydrazine in the presence of Raney nickel in dichlorom ethane solution the amino derivative [B6Cl5(p-C6H4(NH2)]2-is formed. X -ray diffraction analysis has been performed on a single crystal of (Ph4P)2[B6Cl5(p-C6H4(NH2] ·2CH3CN-0,5Et2O(triclinic, space group P1̅, a = 12.870(6), b = 12.9406(5), c = 35,870(7) Å , a = 91,63(4), ß = 93,22(7), γ = 98,04(8)°, Z = 2). The 11B NMR spectrum is consistent with a monosubstituted B6 cluster. The IR and R am an spectra exhibit characteristic BB, CH , CC, and NH vibrations, respectively.
