The title compound belongs to monoclinic, space group P21/c with a = 9.335（5）, b = 20.632（12）, c = 13.853（8） A, β = 107.193（9）°, Mr = 487.46, Z = 4, Dc = 1.270 g/cm^3, μ = 0.293 mm^-1, F（000） = 1015, R = 0.0859 and wR = 0.2633. In the title compound, Na coordinates with N（1）, O（1） and O（3） from one monosulfuron-ester molecule, N（4A） and O（5A） from the other monosulfuron-ester molecule and one oxygen atom from DMSO to give six coordination bonds.展开更多

Herein its sodium salt was firstly synthesized and crystal structure was determined by X-ray diffraction method. The title compound belongs to the triclinic system, space group P1^- with a = 7.306（6）, b = 9.446（8）, c = 11.872（10）A, α = 76.578（14）, β = 78.049（13）, γ = 77.620（14）°, V = 767.7（11）A^3, Mr = 377.32, Z = 2, Dc = 1.632 g/cm^3,μ= 0.283 mm^-1, F（000） = 388, R = 0.0444 and wR = 0.1186. In the title compound, Na（1） coordinates with 0（4） and 0（5） from one monosulfuron molecule, N（4A） and O（5A） from the other monosulfuron molecule and the oxygen atom from H2O to give five coordination bonds. The title complex is further linked into a three-dimensional structure through π…π interactions and intermolecular hydrogen bonds between the oxygen and nitrogen atoms.展开更多
