摘要：

The title compounds, C32H28N2O4, (I), and C32H28N2S4, (II), respectively, are tetrasubstituted pyrazines and both possess C-i symmetry. They differ only in the hetero atom (X) of the -CH2XPh side-arm substituents: X = O in (I) and S in (II). Compound (I) has an overall S-shape with a pair of adjacent -CH2OPh side arms alternately above and below the plane of the central pyrazine ring. The phenyl rings are inclined to one another by 12.63 (18)degrees and there is one intramolecular C - H center dot center dot center dot O hydrogen bond involving adjacent -CH2OPh side arms. In compound (II), adjacent -CH2SPh side arms point in opposite directions with respect to the pyrazine ring plane, with the phenyl rings inclined at 60.45 (8)degrees. Both structures have weak C - H center dot center dot center dot pi intermolecular interactions.
