Description

Crystal structure of KAsUO6 · 3H2O is solved at 100 and 293 K. At 100 K the crystals belong to the tetragonal crystal system, sp. gr. P4/ncc, a =7.2037(6), c = 17.811(2) A; Z=4, R1 = 0.0263, wR2 = 0.0546 for 618 independent reflections; at 293 K the crystals belong to the same crystal system, sp. gr. P4/ncc, a = 7.1600(4), c = 17.746(1) A; Z= 4, R1 = 0.0263, wR2 = 0,0433 for 427 independent reflections. The results of X-ray diffraction study are correlated with the earlier obtained data on specific heat of the compound and the structural changes taking place with an increase in temperature are considered

Abstract (Russian)

Расшифрована кристаллическая структура KAsUO6 · 3H2O при 100 и 293 К. KAsUO6 · 3Н2О при T =100 К: тетрагональная, пр. гр. Р4/ncc, а =7,2037(6), с= 17,811(2) A; Z=4, R1 = 0,0263, wR2 = 0,0546 для 618 независимых рефлексов; при T= 293 К: тетрагональная, Р4/ncc, а = 7,1600(4), с = 17,746(1) A; Z= 4, R1 = 0,0263, wR2 = 0,0433 для 427 независимых рефлексов. Результаты проведенного рентгеноструктурного анализа сопоставлены с полученными ранее данными по теплоемкости этого соединения, и рассмотрены изменения, происходящие в структуре при повышении температуры
