Monosulfuron-ester is a novel sulfonylurea herbicide with ultra-low dosage. Herein sodium monosulfuron-ester was synthesized and its crystal structure was determined by X-ray diffraction method. The title compound belongs to monoclinic, space group P21/c with a = 9.335(5), b = 20.632(12), c = 13.853(8) ’, β = 107.193(9)°, Mr = 487.46, Z = 4, Dc = 1.270 g/cm3, 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.
