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

摘要

The striking resemblance of the rhombohedral and rnonoclinic forms of the title molecule to β- and γ-quinol provides a crystal engineering approach to new polymorphic systems.
