Figure 3
Unit-cell dimensions of (a) ZnAsp2·1.5H2O (open symbols, dashed lines) and (b) ZnAsp2·2H2O (solid symbols and lines), relative to their values at 296 K/0.1 MPa, as a function of pressure. The magnitudes of the unit-cell parameters, including the angular dimensions, are plotted in Figs. S2 and S3. The vertical dashed line in panel (a) indicates the phase transition in ZnAsp2·1.5H2O (see also Fig. S6). The open black symbols in panel (b) show the volume compression in ZnAsp2·1.5H2O relative to the volume of ZnAsp2·2H2O at 0.1 MPa. |
