Abstract: | Crystal Structure of Tetraphenylphosphonium Monothiocyanatohydro-closo-Decaborate, P(C6H5)4]22-(SCN)B10H9] · CH3CN The X-ray structure determination of P(C6H5)4]22-(SCN)B10H9] · CH3CN (monoclinic, space group P21/n, a = 10.6040(10), b = 13.8880(9), c = 33.888(3) Å, β = 94.095(8)°, Z = 4) reveals the S coordination of the SCN substituent with a B? S distance of 1.913(6) Å and a B? S? C angle of 105.3(3)°. The SCN group is nearly linear (178.2(7)°). |
