Fig. 1: Crystal structures of 1D crystals.
From: Parallel-stacked aromatic molecules in hydrogen-bonded inorganic frameworks
Crystal structures of 1D-C (a–c), 1D-W (d–f), and 1D-R (h–l) determined by single-crystal X-ray diffraction. The hydrogen atoms have been omitted for clarity, except for those involved in hydrogen-bonding between Q8H8 molecules in (b and c) (Si: red; O: blue; C: gray; H: white; N: green; hydrogen bonds between Q8H8: orange dashed lines; hydrogen bonds between Q8H8 and co-crystallization solvents: light blue dashed lines). a, d, j Crystal packing; b, e, k 3D space-filling representation of HIF’s network; c, f, l hydrogen-bonding interactions; h polarized micrograph; i crystal photograph with cell axes, which were drawn by CrysAlisPro software. g Scheme of optimized synthetic process of 1.
