Lanthanide-like: X-ray diffraction and density functional theory studies show that [An(H2O)9]3+ ions of the actinides U3+–Cf3+ in crystals of their triflate salts have the same structure and electrostatic bonding as their lanthanide counterparts La3+–Eu3+. Moreover, the nine-coordinate geometry is essentially preserved in solution for the lighter elements (see picture).
