Рентгенографическим методом показано, что полученные поликристаллические образцы являются однофазными. Из дифракционных спектров полнопрофильным анализом по методу Ритвельда с использованием программного пакета Fullprof опре- делены параметры элементарной ячейки синтезированных соединений и твердых растворов Cu2CdSn(SxSe1–x)4. Установлено, что с ростом концентрации серы параметры элементарной ячейки плавно уменьшаются по линейному закону в соответствии с правилом Вегарда, что свидетельствует об образовании в системе Cu2CdSn(SxSe1–x)4 непрерывного ряда твердых растворов в области 0 ≤ x ≤ 1. Рассчитан параметр тетрагональных искажений кристаллической решетки исследованных соединений h. Значения h близки к единице для всех изученных составов, что свидетельствует о малых искажениях кристаллической решетки полученных образцов.</p></abstract><trans-abstract xml:lang="en"><p>The quaternary semiconductors Cu2CdSnS4, Cu2CdSnSe4 and Cu2CdSn(SxSe1–x)4 solid solutions were synthesized by the one-temperature method from the elementary components. The X-ray diffraction method showed that the obtained polycrystalline samples are single-phased. The unit cell parameters of the synthesized compounds and Cu2CdSn(SxSe1–x)4 solid solutions were determined from diffraction spectra by the full-profile analysis using the Rietveld method with the Fullprof software package. It has been established that with an increase in sulfur concentration, the unit cell parameters decrease smoothly linearly in accordance with the Vegard rule, which indicates the formation of a continuous series of solid solutions in the Cu2CdSn(SxSe1–x)4 system within the range 0 ≤ x ≤ 1. The parameter of crystal lattice tetragonal distortions h of the investigated compounds is calculated. The h values are close to 1 for all the compositions studied, which indicates a small crystal lattice distortion of the obtained samples.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>четверные полупроводники</kwd><kwd>параметры элементарной ячейки</kwd><kwd>рентгенографические исследования</kwd><kwd>твердые растворы</kwd><kwd>тетрагональные искажения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quaternary semiconductors</kwd><kwd>cell parameters</kwd><kwd>X-ray investigations</kwd><kwd>solid solutions</kwd><kwd>tetragonal distortions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Thermoelectric properties of tetrahedrally bonded wide-gap stannite compounds Cu2ZnSn1–xInxSe4 / X.
