Figure 2
Pressure dependence of (a) the cell volume at room temperature and (b) the lattice parameters, normalized using the corresponding ambient lattice parameters (Sunshine & Ibers, 1985BB22). Note that the b axis and cell volume are multiplied by 2 in the high-pressure phase region. Low- and high-pressure structures coexist within the shaded area at ∼3 GPa. The solid lines shown in panels (a) and (b) represent data fitting with respect to the equation of state and a guide for the eye, respectively.
