1,2-Diaminoethane in phase Iβ: (a) one single crystal filling the pressure chamber at 1.1 GPa and 296 K; (b) the DAC heated to 423 K with one single-crystal plate left; (c) the single-crystal plate grown to the edges of the chamber after increased pressure; and (d) the single-crystal filling the whole volume of the chamber, when pressure stabilized to 1.5 GPa at 296 K. Miller indices of the crystal faces are indicated in photograph (b). A large (0.1 mm) ruby chip for pressure calibration is placed in the upper-left part of the chamber. |
