(a) Space-group diagrams displaying the symmetry of the mother C2/c (P 1) (top left), daughter P2₁/n (P 2) (bottom left) and P2₁/a (P 3) (right) phases of Form-I. The parts in light blue indicate symmetry elements that are no longer present in the new phases. (b) Overlay of the molecular skeleton of the complexes in the C2/c (P 1) (blue) and P2₁/n (P 2) (red) cells, illustrating the molecular distortion which occurs during the phase change (inset). (c) Overlay of the molecular skeleton of the complexes in the P2₁/n (1.69 GPa, blue) and P2₁/a (2.18 GPa, red) phases to illustrate the molecular distortion which occurs during the phase change. Note the significant movement of the C31 atom through an angle of 129° between the P2₁/n and P2₁/a phases (inset).
