Description

Crystals of the first uranyl bichromate [CH6N3]2[(UO2)(Cr2O7)](H2O) are obtained by the method of evaporation from aqueous solutions. Compound has triclinic symmetry, space group P1-bar, a=7.1829(17), b=9.304(3), c=14.884(4), α=102.43(2), β=97.08(2), γ=101.07(2) Deg, V=936.3(5) A3, Z=2. Unidimensional complexes [(UO2)(Cr2O7)]2- are the basis of the structure. Chains of [(UO2)(Cr2O7)]2- are elongated along x axis and are oriented parallel with (011). Triangular cations [CH6N3]+ and H2O molecules are disposed between chains

Abstract (Russian)

Кристаллы первого бихромата уранила [CH6N3]2[(UO2)(Cr2O7)](H2O) получены методом испарения из водных растворов. Соединение имеет триклинную симметрию, простанственная группа P1-bar, a=7.1829(17), b=9.304(3), c=14.884(4), α=102.43(2), β=97.08(2), γ=101.07(2) град, V=936.3(5) A3, Z=2. Основу структуры составляют одномерные комплексы [(UO2)(Cr2O7)]2-. Цепочки [(UO2)(Cr2O7)]2- вытянуты вдоль оси x и ориентированы параллельно (011). Треугольные катионы [CH6N3]+ и молекулы H2O расположены между цепочками
