Benzylammonium hydrogen oxalate hemihydrate

J. C. Barnes

Abstract: -Aminotoluene (benzylamine) reacts with ethanedioic acid (oxalic acid) to form C₆H₅CH₂NH₃⁺·C₂HO₄^-·0.5H₂O. The monohydrogenoxalate ions form hydrogen-bonded chains [2.558  (1)  Å], linked into pairs by hydrogen bonds [2.758  (1)  Å] to a water molecule lying on a crystallographic twofold axis. Three hydrogen bonds [2.833  (1)-2.896  (1)  Å] from each benzylammonium ion connect these chains into layers.
