Cocrystal and Salts of 2,2′,6,6′-Tetracarboxybiphenyl with Bis(pyridyl) Derivatives: Eight-fold Interpenetrated Diamondoid and Layered Networks
文摘
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-S4) 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.
