In the crystal structure of the title compound, C(14)H(14)N(4)O(2), the mol-ecules are almost planar (mean deviation 0.028 Å) and a weak intra-molecular N-H⋯O hydrogen bond between the H atom bound to an oxamide N atom and a carbonyl O atom is found. The asymmetric unit consits of one half-mol-ecule which is located on a centre of inversion.
