Abstract
Single crystal X-ray structures are presented for three amino acid arenesulfonate salts:l-alanine 2,4-dinitrobenzenesulfonate hydrate (1), 2∶1 glycine 1,5-naphthalene-disulfonate dihydrate (2), andl-serine 4-hydroxybenzenesulfonate (3). Hydrogen bond patterns of each salt are analyzed systematically by using hydrogen bond graph set notation. First-, second-, and selected third-level graph set motifs of the three salts are presented and discussed. Hydrogen-bonded diad, chain, ring, ribbon, and two-dimensional sheet patterns are identified in these structures. Even though the three salts contain apparently similar types of hydrogen-bonding interactions, their graph sets are quite different.
