Combining two distinctive intermolecular forces in designing ternary co-crystals and molecular salts of 1,3,5-trinitrobenzene, 9-anthracenecarboxylic acid and ten substituted pyridines

Abstract

A series of ten ternary complexes, consisting of a charge transfer binary complex hydrogen bonded to a third component, are synthesized using neutral and charge-assisted hydrogen bonding. The colours of the ternary complexes change from yellow to orange to red depending on the identity of the third component, being a number of pyridines with nitro, amino or halogen atom substituents.
