2-Ethyl-imidazolium terephthalate.


ABSTRACT: The asymmetric unit of the title compound, C(5)H(9)N(2) (+)·C(8)H(5)O(4) (-), consists of one protonated 2-ethyl-imidazolium cation and two half terephthalate anions. The anions and cations are linked through N-H?O hydrogen bonds while the anions are associated via O-H?O inter-actions, resulting in a layered structure. The ethyl group of the cation is disordered over twosites of occupancies 0.812?(14) and 0.188?(14). The hydroxy H atoms of the anions are equally disordered over two symmetry-related sites.
