Hydrogen-Bond Triple Hooks in an Inclusion Crystal of Cholanamide with Aniline - Structural Difference of Inclusion Crystals of Cholic-Acid and Cholanamide with Same Guest
Crystal structure of an inclusion crystal of cholanamide with aniline is described. Comparison of the crystal structure with that of the cholic acid clathrate reveals both hosts have quite similar assembly mode. However, the most striking difference is hydrogen bonding. Aniline is included in host lattice of cholanamide by triple hydrogen bonds, whereas in that of cholic acid by double weak hydrogen bonds. Difference of the molecular structure between them gives raise to change the host-guest hydrogen bonding.
