Figure 5
Linear strain in the directions of principal axes of strain ellipsoid versus temperature in phases (I) (a) and (II) (b) of glutaric acid–glycine co-crystal. For both structures the values of linear strain along the principal axes of strain tensor [1 (minimum linear size of strain ellipsoid), 2 (normal to 1 and 3), 3 (maximum linear size of train ellipsoid)] are plotted as squares, circles and triangles, respectively. Ambient temperature is taken as a reference point for phase (I); 200 K for phase (II).
