Аннотация: A concentration series of single crystals of iron-cobalt ludwigites Co3 - x Fe (x) O2BO3 (x = 0.0125, 0.025, 0.050, 0.10, 1.0) has been synthesized. The structure has been studied using X-ray diffraction and Mossbauer effect. A preferred occupation of nonequivalent crystallographic positions by iron in the ludwigite structure has been revealed. It has been found that the valence of substituting iron ions is three. It has been revealed that the structure of the gamma-resonance spectrum of Co2FeO2BO3 is complicated due to a composition disorder in the system.
