Y. Miyake et al., INCLUSION-COMPOUNDS OF HYODEOXYCHOLIC ACID AND THE CRYSTAL-STRUCTURE OF A 1 1-COMPLEX BETWEEN THE ACID AND PYRIDINE/, Chemistry Letters, (12), 1997, pp. 1263-1264
Hyodeoxycholic acid forms inclusion crystals with aromatic amines such
as pyridine, aniline and toluidines. The crystal structure of a I:1 i
nclusion compound of hyodeoxycholic acid with pyridine was determined.
