Figure 5
Unit-cell dimensions of 1,2-diaminoethane crystalline phases plotted as a function of (a) pressure at 296 K and (b) temperature at 0.1 MPa for phases Iα, Iβ, Iγ and III: aIα, aIβ, aIγ (black circles); bIα, bIβ, bIγ (black squares); cIα, cIβ, cIγ (black triangles); aIII (green open circles); bIII (green open squares); cIII (green open triangles). For phase Iγ the aIγ/2 value has been plotted for convenient comparison with other phases. The red points at 0.1 MPa are determined at 274 K. The lines joining the points have been drawn as a guide to the eye. The unit-cell dimensions measured at 213 K by Jamet-Delcroix (1973  ) and in the metastable region at 130 K by Thalladi et al. (2000) have been included. |
