 Abstract    von Am inohexahydro-closo-hexaborat(l-), [B6H6(NH2)]~ sowie Kristallstruktur von Cs[B6H6(NH2)]*H 20 P rep aratio n , n B N M R and V ibrational Spectra of A m in o h e x a h y d ro -c lo so -h ex a b o ra te (l-), [B6H 6(N H 2)]' , and the C rystal S tructure of Cs[B6H 6(N H 2)] • H 20 By reduction of [B6H5(N0 2)]2_ with Fe2+ in aqueous alkaline solution [B6H6(NH2)]~ is formed. The compound has been separated by extraction with dichloromethane in the presence of tetrabutylammoniumbromid and precipitated from the organic phase by adding CsCH3COO/C2H5OH. The Crystal structure of Cs[B6H6(NH2)] H20 has been determined by single crystal X-ray diffraction analysis; monoclinic space group C2 with a = 22.1075(14), b = 6.491(2), c = 5.9570(4) Ä, ß = 100.168(6)°. The UB NMR spectrum is consistent with a mono-hetero-substituted octahedral B6 cage with local C4v symmetry. The IR and Raman spectra exhibit characteristic N -H , B -H and B6 vibrations.
