Abstract
Complexes [Co(solv)n][B10H10], where (I: solv = H2O, n = 6; II: solv = N2H4, n = 3) have been synthesized and characterized. The possibility to use them as precursors in the synthesis of binary borides has been demonstrated. The purity and homogeneity of the precursors and the products of their thermal reduction (in an inert atmosphere at 650 and 900°С) has been established by elemental analysis, X-ray powder diffraction, and IR spectroscopy; magnetochemical studies of the 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 has revealed 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, while the nitride-boride phase, by a diamagnetic contribution.
