An investigation of the inclusion complex of cyclomaltoheptaose (beta-cyclodextrin) with N-methylanthranilic acid in the solid state.
A 2:1 complex between cyclomaltoheptaose (beta-cyclodextrin) and N-methylanthranilic acid has been studied in the solid state. The inclusion complex belongs to the triclinic system (space group P1) with unit cell dimensions a=15.2773(15)A, b=15.4710(15)A, c=17.9627(18)A, alpha=99.632(5) degrees , beta=113.416(5) degrees , and gamma=102.818(5) degrees . The complex forms a head-to-head channel-type structure with the N-methylanthranilic acid lying between the beta-cyclodextrin groups in a sandwich fashion, which is held in place by an extensive hydrogen-bonding network between the cyclodextrin molecules.
