Supramolecular Alcohol-Amine Crystals and Their Hydrogen-Bond Patterns

Journal Article (Journal Article)

An analysis of the structures of five new cocrystals with saturated hydrogen bonding between amines and alcohols is presented. These five are all cocrystals with p-phenylenediamine (PDA) and a mono- or diol. The cocrystals are p-phenylenediamine-phenol (1/2) [PDA·2 phenol, (I)], p-phenylenediamine-p-phenylphenol (1/2) [PDA·2 p-phenylphenol (II)], p-phenylenediamine-2,6-dihydroxynaphthalene (1/1) [PDA·2,6-dihydroxynaphthalene (III)], p-phenylenediamine-1,6-hexanediol (1/1) [PDA-1,6-hexanediol (IV)] and p-phenylenediamine-p-chlorophenol (1/2) [PDA·2 p-chlorophenol (V)]. These crystals have two distinctly different supramolecular hydrogen-bond patterns, when considering only the hydroxyl and amine groups. There are, in addition, variations in the ways covalently bonded crosslinks connect these hydrogen-bond networks. The graph sets of the hydrogen-bond networks of these and other published saturated amine-alcohol crystals are compared and suggestions made on how to present the graph-set descriptions, especially those involving infinite two- and three-dimensional networks of intersecting chains which are characteristic of most of these materials.
