a PFtB anion salt 5. b PFMPA anion salt 6. With thermal ellipsoids at the 30% probability level. The hydrogen atoms are omitted for clarity. Selected bond lengths of 5 (Å): C22−F6 1.360(6), Cs1−F6 3.470(6), C24−F5 1.374(5), Cs1−F5 3.565(4), Cs1−F7 3.230(4). Selected bond lengths of 6 (Å): Cs1−O7 2.994, Cs1−F5 3.663, C23−F5 1.335(7) Estimated standard deviations are in parentheses.
