Abstract
Crystal structure of zwitterionic trimethylammoniopropane sulfonate (Z1-Methyl) was determined by single-crystal X-ray diffractometry. Z1-Methyl crystallized in the monoclinic system, space group P21, with a = 6.3639(2), b = 10.9237(4), c = 8.1505(4)Å, β = 111.078(2)°, V = 528.69(4)Å3, Z = 2. An inter-molecular ionic association was observed in the crystal. The shortest distance between the methyl protons of the trimethylammonium group and the oxygens of the sulfonate group was 2.51(2)Å.
