Crystal chemical studies of the 5<i>f</i>-series of elements. XX. The crystal structure of tripotassium uranyl fluoride

Abstract

KaUO2F 5 is tetragonal with a 1 ----9.1600-001, a a ----18.1670.002 /~ and eight stoichiometric molecules per unit cell. The space group is I41/a. The positions of all light atoms have been determined with considerable accuracy with the aid of precise intensity measurements on a small spherical crystal and a series of generalized Fourier syntheses.
