Description

The structure of NH4[UO2(C2O4)(NCS)] · 2H2O was studied by X-ray diffraction analysis. The crystals are monoclinic; unit cell parameters are as follows: a = 9.129 A, b = 13.102 A, c = 8.981 A, β 99.19 deg, space group C2/c, Z = 4, R = 0.0198. The basic structural units of the crystals are chains of [UO2(C2O4)(NCS)]- composition belonging to the AK02M1 (A = UO22+) crystal-chemical group of uranyl complexes. The uranium-containing complexes are linked in a three-dimensional framework through ammonium ions and a hydrogen-bond array involving outer-sphere water molecules

Abstract (Russian)

Проведено рентгеноструктурное исследование монокристаллов NH4[UO2(C2O4)(NCS)] · 2H2O. Соединение кристаллизуется в моноклинной сингонии, параметры элементарной ячейки: a = 9.129, b = 13.102, c = 8.981 A, β = 99.19 град, пр. гр. C2/c, Z = 4, R = 0.0198. Основными структурными единицами кристаллов являются цепи состава [UO2(C2O4)(NCS)]-, относящиеся к кристаллохимической группе AK02M1 (A = UO22+) комплексов уранила. Урансодержащие комплексы соединены в трехмерный каркас ионами аммония и системой водородных связей, в образовании которых участвуют внешнесферные молекулы воды
