    The first structural measurements on a cyclic sulfamidate, DL-3-benzyl-2,2-dioxo-1,2,3-oxathiazolidine-4-carboxylate, C11H13NO5S, show that die ring N atom has almost planar bonding geometry (sum of angles at N = 357.8-degrees), in contrast to that found in simple dialkyl sulfonamides and acyclic sulfamate esters. The structure contains a close 1,4 N...O contact [2.764 (3) angstrom]
