Diethyl pyrazine-2,5-dicarboxyl-ate.
The mol-ecule of the title compound, C(10)H(12)N(2)O(4), is located around an inversion center. The carboxyl-ate groups are twisted slightly with respect to the pyrazine ring, making a dihedral angle of 2.76 (19)°. In the crystal, mol-ecules are stacked along the c axis via weak C-H⋯O hydrogen bonds.
