The highly interlinked two-dimensional layers in (I) that experience weak interactions via hydrogen bonds originating from coordinating water molecules. Light-grey spheres denote water and hydroxy O atoms, dark-grey spheres carboxylate O atoms, black spheres C atoms, white spheres H atoms, grey and light-grey polyhedra [YbO8] units, and dark-grey polyhedra [YbO7] units. The H atoms bonded to C atoms have been omitted for clarity. |
