Molecular complexes of explosives with cyclodextrins. 2. Preparation and characterization of a solid complex of β-cyclodextrin with the nitramine 1,3,3-trinitroazetidine (TNAZ)

A solid complex between 1,3,3-trinitroazetidine (TNAZ) and β-cyclodextrin has been isolated for the first time and characterized by the application of solution and solid-state NMR techniques, Raman spectroscopy, and differential scanning calorimetry experiments. All the techniques show clear differences in properties of the solid product from those of a simple physical mixture of the components, and when taken together, they provide convincing evidence for the complex formation.
