 Title    Darstellung, UB-, 13C-NM R-und Schwingungsspektren der c/öso-Hexaborate [B6H 5(C N )|2~ und m -[B 6H4(CN)2l2_ sowie Kristallstruktur von Cs2[B6H 5(CN)|  
 Abstract    of the c/oso-Hexaborates [B6H 5(CN)]2~ and c/s-[B6H 4(C N)2]2-, and the Crystal Structure o f Cs2[B6H 5(CN)] By reaction o f Cs2[B6H 6] with in situ generated dicyanogen in aqueous alkaline solution the m onocyanohydrohexaborate C s2[B6H5(CN)] and the dicyanohydrohexaborate cis-Cs,[B6H4(C N)2] are formed. The com pounds have been separated by ion exchange chrom atog­ raphy on diethylaminoethyl cellulose. The crystal structure o f Cs2[B6H5(CN)] was determined from single crystal X-ray diffraction analysis; monoclinic, space group P 2 Ja with a = 9.540(8), b = 9.977(3), c = 10.578(2) Ä, ß = 105.06(2)°. The B6 octahedron is compressed in the direction o f the nearly linear B -C N bond by about 5%, with bond lengths between 1.71 and 1.76Ä . The "B N M R spectra o f the two com pounds reveal the features o f substituted B6 cages with C4v and C2v point symmetry. In the l3C N M R spectrum o f Cs2[B6H 5(CN)] a quartet at -139 ppm with '/(C ,B) 92 Hz is observed. The IR and Raman spectra exhibit very strong CN stretching bands for Cs2[B6H5(CN)] at 2149, and for m -C s2[B6H4(C N)2] at 2170 c tr r 1.
