N2 - The compound Ag2[(UO2)6(MoO4)7(H2O)2](H2O)2 was prepared at 220°C in the course of hydrothermal synthesis. The phase crystallizes in the rhombic system, space group Pbcm, a = 14.1309(9), b = 10.6595(7), c = 25.8281(16) Å, V = 3890.44 Å3. The crystal structure was solved by direct methods and refined to R 1 = 0.049 for 4394 reflections with Fo > 4σ(Fo) and 0.1025 for all the 8239 reflections. The structure is based on a framework constituted by UO7 and MoO4 polyhedra sharing common vertices. In the framework, there are two systems of channels occupied by Ag+ cations and water molecules and oriented along [001] and [010].
