Figure 5
Octahedral frameworks of two structures with a single tilt mode (a) X3+(a, a) tilt mode (1863837) and (b) X2+(0, a) rotation mode (2016195). Note the out-of-phase tilting around the ab plane and alternating direction of tilts in (a) and the absence of layer-plane tilting but presence of rotations of the same degree around the c axis in (b).
