title: Dimethyl N,N'-oxalamidodiethanoate.
abstract: The title compound, dimethyl 2,2'-(oxalyldiimino)diethanoate, C(8)H(12)N(2)O(6), exhibits a network of hydrogen bonds between amide and ester groups. Molecules lie on inversion centres and show a planar conformation for both the oxalamide and ester groups. The glycine residues adopt a conformation close to the polyglycine II structure.
