Designing a non-centrosymmetric crystal: structure of 4′-cyano-2,6-dimethyl-4-hydroxyazobenzene
Abstract
Utilising the preferential adoption of hydroxy–cyano hydrogen bond over the hydroxy–hydroxy hydrogen bond in molecular crystals, the crystal structure of 4′-cyano-2,6-dimethyl-4-hydroxyazobenzene is designed into an acentric space group.
