From: Parallel-stacked aromatic molecules in hydrogen-bonded inorganic frameworks
Crystal structures of 2D-S (a–e), and 2D-MS (f–i) determined by single-crystal X-ray diffraction. The hydrogen atoms have been omitted for clarity (Si: red; O: blue; C: gray; hydrogen bonds between Q8H8: orange dashed lines; hydrogen bonds between Q8H8 and co-crystallization solvents: light blue dashed lines). a Polarized micrograph; b crystal photograph with cell axes, which were drawn by CrysAlisPro software; c crystal packing; d 3D space-filling representation of HIF’s network; e, i hydrogen-bonding interactions; f top, g side, and h oblique space-filling views of three layers of the stacked mesh sheets of 2D-MS (co-solvent molecules omitted for clarity), in which the first, second, and third layers are colored light blue, pink, and green, respectively.
