Restraints extracted from molecule-in-cluster optimizations of separate disorder components permit improved least-squares modelling of experimental crystal structures, and considering energy barriers alongside enthalpy differences further enables the distinguishing of disorder into static and dynamic.

Two dioxala-benzenacyclononaphanes differ principally by the presence of a pyrrolizine ring system in one and a pyrrolothiazole ring system in the other. In the crystal of the former, molecules are linked via C—H
N and C—H
O hydrogen bonds, forming sheets parallel to (10
) while in the latter, molecules are linked via C—H
N, C—H
O and C—H
S hydrogen bonds, forming slabs parallel to (001).

A comprehensive review of hybrid lead halide perovskites based on [PbX4]∞ layers is presented. We use a crystallographic approach based on symmetry mode analysis to systematize key types of distortions, particularly octahedral tilting and layer shifts, in this extensive and diverse family of materials.
