Biryukov, Y.P. Crystal structure refinement, low- and high temperature X-ray diffraction and Mössbauer spectroscopy study of the oxoborate ludwigite from the Iten'yurginskoe deposit / Biryukov, Y.P., Zinnatullin, A.L., Levashova, I.O., Vagizov F,...Filatov, S.K., Pekov, I.V. // Acta Crystallographica Section B: Structural Science, Crystal Engineering and Materials, - 2023, - V. 79, - p. 368–379

Аннотация

his paper reports an investigation of the chemistry, crystal structure refinement and thermal behavior (80–1650 K) of ludwigite from the Iten'yurginskoe deposit (Eastern Chukotka, Russia). Its chemical composition was determined by electron microprobe analysis, giving an empirical formula (Mg1.70Fe2+0.29Mn0.01)Σ2.00(Fe3+0.90Al0.08Mg0.02)Σ1.00O2(BO3). A refinement of the crystal structure from single-crystal X-ray diffraction data (SCXRD) was provided for the first time for ludwigite from this deposit (R = 0.047). The structure can be described as a framework composed of [MO6]n− octahedra and isolated [BO3]3− triangles located in triangular interstices of the framework. Based on a comprehensive analysis of SCXRD and Mössbauer spectroscopy data, the M1 site is occupied by Mg, M2 and M3 by Mg and Fe2+, M4 by Fe3+, Mg and Al.
