meso-N, N-Oxalyldivaline

The title compound, 2, 2' -(oxalyldiimino)bis(3-methylbutanoic acid), C12H20N2O6, possesses a centre of symmetry. In the crystal, molecules are connected by hydrogen bonds between oxamide and carboxyl groups, similar to the pattern of the monoclinic forms of HO-Gly-CO-CO-Gly-OH hand HO- Aib-CO-CO-Aib-OH (Gly is glycine and Aib is 2-aminoisobutyric acid). The characteristic torsion angles in the title compound are close to those in peptide alpha -helices.
