Diethyl<i>N,N</i>′-<i>o</i>-phenylenedioxamate

Abstract

The crystal structure analysis of the title compound, C6H4(NHC2O3C2H5)2 or C14H16N2O6, reveals a mol­ecule with both oxamate groups twisted with respect to the benzene ring, as a result of steric interactions and the presence of three strong N—H⋯O and one weak C—H⋯O intramolecular hydrogen bonds. Centrosymmetrically related mol­ecules form dimers connected by two N—H⋯O hydrogen bonds.
