Abstract
The title compound, C6H8N2O2, 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. π–π interactions between neighboring 2,5-dimethylpyrazine 1,4-dioxide molecules are observed with an interplanar distance of 3.191 Å. Each 2,5-dimethylpyrazine 1,4-dioxide molecule is linked to four neighboring N-oxide molecules through C—H⋯O hydrogen-bonding interactions, forming two-dimensional layers.
