Three structures are reported: l-benzylimidazolium phenylphosphonate, 2-ethylimidazolium phenylphosphonate, and 2-methyl imidazolium phenylphosphonate. Of these three salts two, 2-ethylimidazolium phenylphosphonate and 2-methylimidazolium phenylphosphonate, are noncentrosymmetric and therefore display a nonlinear optical response. jg. 收起
