Shape and size mimicry in the design of ternary molecular solids: towards a robust strategy for crystal engineering

Abstract

2- and 5-methylresorcinol form co-crystals with 4,4′-bipyridine in which some of the bipyridine molecules are loosely bound. These molecules can be replaced with other molecules of a similar shape and size to give a general method for the engineering of a ternary co-crystal.
