    Abstract

    Herein we describe a straight-forward and reproducible method for the preparation of homogeneous, multicomponent cocrystals and supramolecular solid solutions. We prepared these multicomponent materials based on small organic molecules that employ a two-point supramolecular hydrogen bond synthon. We report the creation and characterization of two, three, four, five, and seven component crystals containing a variety of 2-aminopyridines and monosubstituted benzoic acids. These systems exhibit the ability to accommodate multiple components in varying proportions while coordinating into an identical packing structure. The flexibility of the system to incorporate multiple components also gives rise to gradual modulation of physical properties.
