 Title    Darstellung, "B-NMR-und Schwingungsspektren der ctoso-Hexaborate |B6(SCN)6]J-und [B6(SeCN)6]2  
 Abstract    On treatment o f [N(C4H 9)4][B6H 7] with (S C N)2 or (SeC N)2 in dichloromethane in the pres­ ence o f solid KOH the hexaborates [N(C4H 9)4]2[B6(SC N)6] and [N(C4H9)4]2[B6(SeC N)6] are formed. The octahedral structure for the B6 cage is proven by "B N M R spectroscopy. The chemical shifts in relation to BF3 • OEt2 o f —9,7 (SC N) and -10,2 ppm (SeC N) show the influ­ ence o f -I and +M effects o f the substituents. The S(Se) coordination is deduced from vibra­ tions within the substituents: vCN is observed at frequencies higher than 2100 cm -1 in the IR and Raman spectra, vcs at 662 and vcs at 556 cm "1 (intense IR bands).
