Abstract
By reduction of [B6Cl5(p-C6H4(NO2))](2-) with hydrazine in the presence of Raney nickel in dichloromethane solution the amino derivative [B6Cl5(p-C6H4 (NH2))](2-) is formed. X-ray diffraction analysis has been performed on a s ingle crystal of (Ph4P)(2)[B6Cl5(p-C6H4(NH2))]. 2CH(3)CN .0.5Et(2)O (tricli nic, space group P (1) over bar, a = 12.870(6), b = 12.9406(5), c = 35,870( 7) Angstrom, alpha = 91,63(4), beta = 93,22(7), gamma = 98,04(8)degrees, Z = 2). The B-11 NMR spectrum is consistent with a monosubstituted B-6 cluste r. The IR and Raman spectra exhibit characteristic BB, CH, CC, and NH vibra tions, respectively.
