Cocrystal and Salts of 2,2′,6,6′-Tetracarboxybiphenyl with Bis(pyridyl) Derivatives: Eight-fold Interpenetrated Diamondoid and Layered Networks

Abstract

The cocrystallization reactions of 2,2′,6,6′-tetracarboxybiphenyl with bis(4-pyridyl) ethylene and 4,4′-bipyridine were studied, and it was found that molecular symmetry (pseudo-S 4 ) has been transferred into supramolecular symmetry to form an 8-fold interpenetrated diamondoid network only in the case of cocrystals but not in the case of salts.
