The crystal structure of the 1:1 inclusion complex of beta-cyclodextrin with benzamide.
The 1:1 inclusion complex of beta-cyclodextrin and benzamide was prepared and characterized by single crystal X-ray diffraction, PXRD, TGA, and IR. This complex crystallizes in the monoclinic P2(1) space group with unit cell constants a=15.4244(16), b=10.1574(11), c=20.557(2)A, beta=110.074(2) degrees , V=3025.1(6)A(3). The guest molecule projects into the beta-cyclodextrin cavity from the primary hydroxyl side. The amide group protrudes from the primary hydroxyl side and forms hydrogen bonds with the adjacent beta-cyclodextrin molecule. There are six crystallized water molecules, which play crucial roles in crystal packing.
