Figure 7
Space-filling plots showing the contraction of voids which occur in salicylaldoxime phase I with the application of pressure. The top and bottom rows correspond to the salicylaldoxime-I structure at ambient pressure and at 5.28 GPa, respectively. (a) and (b) show the structure with the a* direction vertical; there are large voids between the molecules, which almost disappear completely with increasing pressure. (c) and (d) show the void between molecules related by the n-glide; this gap also closes up considerably with the application of pressure. |
