Honeycomb molecular network based upon a hydrate of 4, 6‐dichlororesorcinol and the photoproduct rtct‐tetrakis(pyridin‐4‐yl)cyclobutane. Issue 2 (22nd January 2021) - Santana, Carlos L.
Abstract : The formation of a self‐interpenetrated honeycomb molecular network based upon 4, 6‐dichlororesorcinol, water, and the photoproduct rtct ‐tetrakis(pyridin‐4‐yl)cyclobutane is reported. The photoproduct acts as a three‐connected node to form a honeycomb network that contains channels running along the crystallographic b axis. Abstract : The formation of a self‐interpenetrated honeycomb molecular network based upon 4, 6‐dichlororesorcinol (4, 6‐diCl res ), a water molecule, and the photoproduct rtct ‐tetrakis(pyridin‐4‐yl)cyclobutane ( rtct ‐TPCB ) is reported. Interestingly, only three of the four pyridine rings on the central cyclobutane ring are found to engage in O—H…N hydrogen bonds with either the 4, 6‐diCl res or an included water molecule, resulting in a three‐connected net. Notably, the solid (4, 6‐diCl res )·( rtct ‐TPCB )·(H2 O), C6 H4 Cl2 O2 ·C24 H20 N4 ·H2 O, contains channels that run along the crystallographic b axis, which are found to be interpenetrated. Although rtct ‐TPCB has been employed as a bridging ligand in the formation of numerous metal–organic materials, surprisingly neither the single‐component X‐ray structure nor any multi‐component molecular solids based upon this stereoisomer have been reported previously. Lastly, the single‐crystal X‐ray structure of the photoproduct rtct ‐TPCB is also reported.
