Abstract

Cocrystals of the FDA-approved boron-containing API Tavaborole (AN2690) were obtained through solvent evaporation with coformers functionalized with 4-pyridyl groups. The components form three- and four-component supramolecular assemblies sustained by a combination of (B)OH⋯Npyr hydrogen bonds and C-H⋯F interactions, as demonstrated by single-crystal X-ray diffraction analysis. Three cocrystals are isostructural.
