Figure 2
1,2-Diaminoethane in phase III – several stages of the single-crystal growth in the high-pressure chamber: the single-crystal grain at (a) 383 K, (b) 353 K, with Miller indices of the crystal faces indicated, and (c) 323 K; (d) the crystal almost completely filling the chamber, when pressure stabilized to 0.3 GPa at 296 K. A small ruby chip for pressure calibration is visible at the bottom of the chamber in this photograph. |
