Topology of the UOH layers (red lines) and the distribution of interlayer constituents in (a) agrinierite and (b) rameauite. The agrinierite UOH sheet is based on the α-U3O8 type with rods of pentagons and rods of pentagons linked with triangles (oriented up and down). The sheet in rameauite is based on the β-U3O8 type with rods of pentagons linked with triangles (oriented up and down) and rectangles. Color scheme: Ca/Sr sites are pink, K sites are green, blue spheres are O of molecular H2O, black dots within the sheets are OH groups.
