Concomitant polymorphs of 2,2′,6,6′-tetramethyl-4,4′- terphenyldiol: The β-quinol network reproduced in a metastable polymorph

Abstract

The striking resemblance of the rhombohedral and monoclinic forms of the title molecule to β- and γ-quinol provides a crystal engineering approach to new polymorphic systems. © The Royal Society of Chemistry 2005.
