Arylhydrohexaborate

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 dif- fraction analysis has been performed on a single crystal of (Ph4P)2[B6Cl5(p-C6H4(NH2))] · 2CH₃CN·0,5Et₂O (triclinic, space group P1¯,a= 12.870(6),b= 12.9406(5),c= 35,870(7) A˚ ,α= 91,63(4),β= 93,22(7),γ= 98,04(8)∞,Z= 2). The¹¹B NMR spectrum is consistent with a mono- substituted B₆cluster. The IR and Raman spectra exhibit characteristic BB, CH, CC, and NH vibrations, respectively.
