5-Amino-1H-1,2,4-triazol-4-ium hydrogen oxalate

M. Essid, H. Marouani, S. S. Al-Deyab and M. Rzaigui

Abstract: In the title salt, C2H5N4+·C2HO4-, the hydrogen oxalate anions form corrugated chains parallel to the c axis, linked by intermolecular O-H...O hydrogen bonds. The 5-amino-1H-1,2,4-triazol-4-ium cations are connected into centrosymmetric clusters via weak C-H...N hydrogen bonds forming nine-membered rings with an R33(9) motif. These clusters are interconnected via anions through N-H...O hydrogen bonds, building a three-dimensional network.
