Synthesis and crystal structure determination, of Pb2[UO2][TeO3]3

Abstract

Abstract Single crystals of Pb2[UO2][TeO3]3 were obtained by hydrothermal synthesis. The crystal data are: a = 11.605(4), b = 13.389(17), c = 6.981(l)Å, β = 91.23(3)°, Z = 4, D x = 7.42(1)g·cm−3. The structure was determined from X-ray intensities measured on a two-circle diffractometer and was refined for 2566 independent observed reflections to R = 0.059. It can be described as built up by {[UO2][TeO3]3}n 4n− sheets parallel to (010) which are connected by lead atoms in irregular coordination.
