(a) Compression and thermal expansion of the molecular volume and (b) compression of the unit-cell dimensions of C4H2N5Cl (open symbols) and C4H2N5Cl·xH2O (full symbols). The compression line for the partial hydrate α′-C4H2N5Cl·xH2O (through one experimental point) is drawn parallel to that of the anhydrate α′-C4H2N5Cl as a guide for the eye only. All estimated standard deviations are smaller than the plotted symbols; the highlighted sections mark the corresponding dimensions of the α and α′ phases.
