22 space-group changes.
This paper reports 22 examples of space-group changes from low to higher symmetry. The revisions involve 15 crystal structures that were originally described in space group P2(1), six in P1 and one in P1. The relevance of higher-symmetry elements is discussed in connection with the crystallography, the molecular dimensions and, when possible, the spectroscopic properties.
