3-(1-Methyl-3-imidazolio)propanesulfonate: a precursor to a Brønsted acid ionic liquid
نویسندگان
چکیده
The title compound, C(7)H(12)N(2)O(3)S, is a zwitterion precursor to a Brønsted acid ionic liquid with potential as an acid catalyst. The C-N-C-C torsion angle of 100.05 (8)° allows the positively charged imidazolium head group and the negatively charged sulfonate group to inter-act with neighboring zwitterions, forming a C-H⋯O hydrogen-bonding network; the shortest among these inter-actions is 2.9512 (9) Å. The C-H⋯O inter-actions can be described by graph-set notation as two R(2) (2)(16) and one R(2) (2)(5) hydrogen-bonded rings.
