Abstract
By reaction of [B6H6](2-) With (SCN)(2) in dichloromethane at -80 C de grees the thiocyanatohexaborate anion is formed and can be isolated by ion exchange chromatography on diethylaminoethyl (DEAE) cellulose. Th e X-ray structure determination of Cs-2 [B6H5(SCN)] (orthorhombic, spa ce group Pbca with a = 9.506(5), b = 10.644(5), c = 21.857(5) Angstrom , Z = 8) reveals that the SCN substituent is bonded via the S atom wit h the B-S distance of 1.885(9) Angstrom and the B-S-C angle of 99.8(5) degrees. The SCN group is nearly linear (179.9(9)degrees).
