We report on the supramolecular synthesis and characterization of examples from three series of mixed-ligand coordination complexes composed of copper(II), a drug, and an ancillary ligand (AL). Particularly, we demonstrate how the judicious choice of an ancillary ligand affords a large degree of control over the relative lipophilicity/hydrophilicity of the complex in relation to the uncomplexed drug molecule. Furthermore, we demonstrate several important factors to consider in the design of such complexes such as the additive-constitutive nature of the partition coefficient of the ancillary ligand and the relative size of the two types of ligands.

A series of crystalline mixed-ligand copper(II)−aspirinate coordination complexes have been synthesized, structurally characterized, and shown to exhibit a diverse range of pharmacologically relevant properties, such as bulk solubility, solubility ratio (S wo/S ow), and partition coefficient.
