Crystal structure depictions of SCU-8. a Coordination geometry of Th4+, b The cationic cluster of [Th3(COO)9O(H2O)3.78]+ as the SBU, c Hexagonal tubular channels in the structure, d A view of the cationic mesoporous framework structure along c axis. The carboxylate group (O3, O4), coordinating water (O6) and bptc3− ligand are disordered, and only the major conformations are shown. Atom colors: Th = green, O = purple, C = gray
