Crystal packing of L-Met at (a) 293 K, (b) 320 K and (c) 405 K viewed along the b-axis with C atoms of molecule A colored in dark grey and those of molecule B in light grey. As in previous packing diagrams, only the most populated side-chain conformation is shown for each molecule. The length of the gray double arrow at 293 K represents the distance between the centers of neighboring molecular bilayers [calculated as c·sin(β)]. Arrows of the same length at 320 and 405 K illustrate the expansion perpendicular to the molecular bilayers as a function of temperature and phase transitions.
