Fig. 9. (A) Chemical structures of bile acid-l-methionine methyl ester conjugates and ORTEP10 plots of asymmetric units of compounds 6a–c; (B) temperature-dependent diffraction patterns of xerogel of compound 6a together with a simulated pattern of the low-temperature single crystal structure 6a; (C) overlays of (a) molecular structures and (b) packing modes of single crystal X-ray structure (dark structure) and structure solved using XRPD (light structure) presented along the b-axis of the room-temperature structure 6a. For clarity, the sulfur atom (s1) of room temperature structure is presented in a ball-style and hydrogen atoms are omitted. Reproduced with permission from ref. 45 © Royal Society of Chemistry.
