Figure 9
Least-squares overlay of the structures of 4a (red) and 4b (blue) using the non-H atoms for one of the two ion pairs of the asymmetric unit (r.m.s. fit value = 0.152), ignoring water and solvent molecules, and disorder. When extending the fit to the atoms of both ion pairs of the unit cell, the r.m.s. value increases to 0.195, showing the lattice mismatch between 4a and 4b. |
