| Kurze inter-und intramolekulare W asserstoffbrückenbindungen in sauren Salzen halogensubstituierter Orthophthalsäuren Short Inter-and Intram olecular Hydrogen Bonds in Acid Salts of Halogen-Substituted o-Phthalic Acids  | | | Abstract
| The hydrogen bonding in several acid salts o f 4,5-dichlorophthalic, 3,6-dichlorophthalic and 3-fluorophthalic acid have been studied by IR spectroscopy and X-ray structure analysis. N H 4H [3,6-C12C8H 204] and KH[3-FCgH 30 4], with 0 ---0 distances o f 247 and 254.1(4) pm, respectively, belong to Speakm an's type B2 of acid salts o f dicarboxylic acids. In N H 4H[4,5-C12C8H 20 4] • H 20 a short hydrogen bond o f 253(1) pm is form ed to the H 20 m olecule. A very short intramolecular hydrogen bond o f only 234.0(10) pm length was found in N (C 4H 9)4H[4,5-C12C8H 20 4], In the [3,6-Cl2C8H 20 4]2_ dianion both carboxylate groups are nearly orthogonal to the phenyl ring. | | |
