The title compound, C(6)H(8)N(2)O(2), was prepared from 2,5-dimethylpyrazine, acetic acid, and hydrogen peroxide. The 2,5-dimethylpyrazine 1,4-dioxide molecule is located on an inversion center. pi-pi interactions between neighboring 2,5-dimethylpyrazine 1,4-dioxide molecules are observed with an interplanar distance of 3.191 angstrom. Each 2,5-dimethylpyrazine 1,4-dioxide molecule is linked to four neighboring N-oxide molecules through C-H center dot center dot center dot O hydrogen-bonding interactions, forming two-dimensional layers.
