N2 - Yellowish crystals of K2[(UO2)As2O 7] (1) have been synthesized by solid-state reactions method. The structure of 1 [orthorhombic, Pmmn, a = 12.601(2), b = 13.242(2), c = 5.621(1) Å, V = 937.9(3) Å3, Z = 4] has been solved by direct methods and refined ' to R1 = 0.049, wR2 = 0.1060 for 1059 observed reflections. The structure of 1 is based upon [(UO2)As 2O2]2- sheets formed by corner sharing between [UO6]6- distorted octahedra and [As2O 7]4- polyarsenate groups. The K2 cations are either in eightfold or tenfold coordination and are located between the sheets. The topology of the uranyl arsenate sheet is related to silicate minerals of the melilite group and related synthetic silicate, aluminate and germanate compounds.
