N2 - 1H and 13C NMR spectroscopy as well as the FAB mass spectrometry have been applied to six bis[tris(pyrazol‐1‐yl)borates]Co(ll) and one bis[tetrakis(pyrazol‐1‐yl)borate]Co(ll). These octahedral complexes are paramagnetic and it was therefore very difficult to obtain their 13C NMR. The isotropic shifts are very large and characteristic of the different positions of the pyrazole and the boron substituents. FAB‐MS also is an interesting method to characterize these complexes, since they give abundant molecular ions and specific fragmentation. Copyright © 1995 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim
