- Abstract
Hydrogen-bonded directed assemblies of one binary co-crystal was validated by single-crystal X-ray diffraction analysis. The supramolecular reaction between symmetric fumaric acid and 1H-benzotriazole produced molecular co-crystal formulated as [(C6H5N3)•(C4H4O4)0.5] in high yields. Compound contains fumaric acid/1H-benzotriazole in 3:2 ratios and displays a 3D (three-dimensional) H-bonded supramolecular structure. The predominant driving force in co-crystal is hydrogen bonds, by which the compound assemble into supramolecular organic framework. With the presence of the reliable hydrogen-bonding donor/acceptor(s) of fumaric acid, the crystalline lattice of co-crystal is managed by O–H•••N and N–H•••O to afford one-dimensional (1D) acid-base hydrogen-bonding tapes extending along the b axis direction, which are further extended to distinct 3D arrays via primary synthons (the corresponding N–H•••N and C–H•••O interactions). This structural study shows that fumaric acid is a supramolecular reagent that can produce well-defined supermolecule in very high yield.
