Open network structures from 2D hydrogen bonded networks: diaminotriazyl tetraoxapentacenes

Abstract

Crystals of a tetraoxapentacene derivative bearing two diaminotriazine groups exhibit hydrogen-bonded sheets formed by the characteristic hydrogen bonding patterns of the diaminotriazines. By virtue of the large tetraoxapentacene moieties that are oriented perpendicular to the diaminotriazines, these sheets are unable to pack closely, leading to the formation of open network structures with a considerable volume accessible to guest molecules.
