In the title compound, C(12)H(11)N(5)O(2), the mol-ecule adopts an E configuration, with the benzene and pyrazine rings located on opposite sides of the N=C double bond. The face-to-face separations of 3.413 (14) and 3.430 (8) Å, respectively between parallel benzene rings and between pyrazine rings indicate the existence of π-π stacking between adjacent mol-ecules. The crystal structure also c...
