Abstract:
The title compound, C(6)H(8)N(2)O(2), was prepared from 2,5-dimethyl-pyrazine, acetic acid, and hydrogen peroxide. The 2,5-dimethyl-pyrazine 1,4-dioxide mol-ecule is located on an inversion center. π-π inter-actions between neighboring 2,5-dimethyl-pyrazine 1,4-dioxide mol-ecules are observed with an inter-planar distance of 3.191 Å. Each 2,5-dimethyl-pyrazine 1,4-dioxide mol-ecule is linked to four neighboring N-oxide mol-ecules through C-H⋯O hydrogen-bonding inter-actions, forming two-dimensional layers.
