Abstract


In this work, complexes [Co(solv)n][B10H10] (I: solv = H2O, n = 6; II: solv = N2H4, n = e synthesis of binary borides is shown. The purity and homogeneity of the precursors and the products of their thermal reduction (in an inert atmosphere at 650 and 900 °C) has been established by the methods of elemental analysis, X-ray powder diffraction, and IR spectroscopy; magnetochemical studies of precursors and their annealing products have been carried out. According to the data obtained, the reduction products are structured oxide-boride and nitride-boride phases, respectively. Magnetochemical study of the phases showed a significant difference in their magnetic behavior: the oxide-boride phase is characterized by a significant ferromagnetic contribution to the total magnetization of the sample, and the nitride-boride phase is diamagnetic.
