Abstract

An algorithmic strategy to design stoichiometric quaternary and solid-solution quinary solids is described. The strategy involves recognition of structural inequivalences to generate ternary and quaternary cocrystals which can then be extended to five-component solid solutions through matching of suitable interactions.

Keywords: cocrystals; combinatorial approaches; crystal engineering; multicomponent crystals; structural inequivalence.
