Abstract

The flux synthesis, solid state synthesis, and characterization of a new aluminate, Cs(UO)AlO, are reported. Cs(UO)AlO crystallizes in the tetragonal space group I4/ amd with lattice parameters a = 7.3254(2) and c = 30.9849(7) and is constructed from edge-sharing chains of UO pentagonal bipyramids that are connected to [AlO] two-dimensional sheets. The cesium cations, which are heavily disordered, occupy small channels in the a and b directions in the framework structure. The optical properties and ion exchange behaviors are reported along with DFT calculations that support the observed results of the ion exchange experiments.
