Crystal Structure of Zwitterionic Surfactant 3-(N,N-Dimethylmyristylammonio)propane Sulfonate

Abstract

The crystal structure of zwitterionic surfactant 3-(N,N-dimethylmyristylammonio) propane sulfonate (C₁₄N3S) was determined by single-crystal X-ray diffractometry. C₁₄N3S crystallized in the triclinic system, space group P1, with a = 5.6939(7), b = 8.3972(9), c = 24.663(3)Å, α = 84.649(1)°, β = 88.071(1)°, γ = 83.700(7)°, V = 1166.6(2)ų, Z = 2. An inter-molecular ionic association was observed in the crystal. The shortest distance between the methyl protons of the dimethylammonium group and the oxygens of the sulfonate group is 2.26(5)Å.
