a C2/c (α) structure and (b) P21/n (β) structure as viewed along the b-axis. Acetonitrile molecules have been omitted for clarity. Teal and purple atoms correspond to Na/K, yellow, gray, and blue atoms correspond to S, C, and N, respectively, and the polyhedra represent the lanthanide and actinide ions.
