По данным высокотемпературной монокристальной дифракции рассчитаны структуры полиморфных модификаций PdBi2 при температурах 300, 373, 473, 573 и 637 К. В диапазоне температур от 300 К (27 °C) до 573 K (300 °С) существует низкотемпературная модификация α-PdBi2, соответствующая минералу фрудиту, которая характеризуется моноклинной сингонией и пространственной группой C2/m (a = 12,726(1)A, b = 4,2605(4)A, c = 5,5668(5)A, β = 102,51(1) °, V = 299,95(5)A3, Z = 2). При температуре 673K (400 °С) зафиксирована высокотемпературная модификация β-PdBi2, обладающая тетрагональной сингонией и пространственной группой I4/mmm (a = 3,3876(3) A, c = 13,092(2) A, V = 150,24(4) A3, Z = 1), являющаяся аналогом минерала урванцевита. Фазовый переход относится к переходу I типа и является реконструктивным полиморфным превращением с перестройкой I координационной сферы.</p></abstract><trans-abstract xml:lang="en"><p>The phase transition in the structure of the PdBi2 compound was studied using high-temperature in-situ methods (differential thermal analysis, high-temperature single-crystal X-ray diffraction). The structures of PdBi2 polymorphic modifications were refined at temperatures of 300, 373, 473, 573 and 637 K based on the high-temperature single-crystal X-ray diffraction data. A low-temperature modification of α-PdBi2 is monoclinic, space group C2/m (a = 12.726(1)A, b = 4.2605(4)A, c = 5.5668(5)A, β = 102.51(1) °, V = 299.95(5)A3, Z = 2). It is stable in the temperature range from 300K (27 °C) to 573K (300 °С) and is corresponding to the mineral froodite. A high-temperature modification of β-PdBi2 was fixed at the temperature 673K (400 °C). The phase β-PdBi2 is structural analogue of the mineral urvancevite: it’s tetragonal, space group I4/mmm (a = 3.3876(3) A, c = 13.092(2) A, V = 150.24(4) A3, Z = 1). The phase transition refers to a type I and is a reconstructive polymorphic transformation with a rearrangement of the first coordination sphere.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фрудит</kwd><kwd>урванцевит</kwd><kwd>полиморфный переход</kwd><kwd>висмутид палладия</kwd><kwd>высокотемпературная дифрактометрия</kwd><kwd>дифференциально-термический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>froodite</kwd><kwd>urvantsevite</kwd><kwd>polymorphic transition</kwd><kwd>palladium bismuthide</kwd><kwd>high-temperature X-ray diffraction</kwd><kwd>differential thermal analysis</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">Бюргер М.Дж.
