Investigation of the thermal properties of triphenylphosphonium p-toluenesulfonates, which are high temperature ionic liquids, reveals that they solidify to a noncrystalline material on fast cooling from the melt. During the study, a second crystalline form of [1-(methoxycarbonyl) ethyl] triphenylphosphonium p-toluenesulfonate (form II) has been obtained. Form II is monoclinic P21/c, with a = 11.002(5)Å, b = 12.793(5)Å, c = 18.805(5)Å, and β = 102.498(5)°. Comparison with form I reveals the existence of a common robust structural feature involving interactions between cations and anions. © 2009 Springer Science+Business Media, LLC.
