title: Methyl 3-oxo-2,3-dihydro-1,2-benzothia-zole-2-acetate 1,1-dioxide.
abstract: The title mol-ecule, C(10)H(9)NO(5)S, is composed of two essentially planar units with a dihedral angle of 89.16 (6)° between them. In the crystal structure, there are weak inter-molecular C-H⋯O inter-actions resulting in dimeric pairs of mol-ecules about inversion centres and chains of mol-ecules extended along the a and c axes, thus stabilizing the structure. In addition, benzothia-zole rings lying parallel to each other with centroid-centroid distances of 3.679 (2) and 3.999 (2) Å indicate the existence of π-π stacking inter-actions.
