Notizen:
The reaction B(NCS)4- + BX4- (X = F, Cl, Br) leads to mixed BXn(NCS)4-n- (n = 1, 2, 3) species easily detected in solution by 11B NMR. Further, with X = Cl, 1J(11B, 14N) values could be measured from the 11B NMR spectra (25.6, 24.5 and 21.4 Hz for n = 3, 2 and 1, respectively). For X = F, the relevant 1J(11B, 14N) values (24.3, 25.2 and 28 Hz for n = 3, 2 and 1, respectively) increase in the same order as the related 1J(11B, 19F) (5.5, 12.7 and 20.0 Hz, respectively). No such 1J(11B, 14N) could be resolved for X = Br.
