title: Diethyl N,N'-(p-phenylene)dioxamate.
abstract: In the crystal structure, the mol-ecule of the title compound, C(14)H(16)N(2)O(6), is located on an inversion centre. The amide -NHCO- plane makes a dihedral angle of 34.08 (9)° with the benzene ring. The mol-ecules are connected via inter-molecular O-H⋯N hydrogen bonds into a two-dimensional network parallel to the bc plane. An intramolecular N-H⋯O hydrogen bond is also observed.
