| Summary: | In the crystal structure of the title compound, C11H6N4, neighbouring molecules are linked into inversion dimers through pairs of weak C—H...N hydrogen bonds, forming an R22(10) ring motif. The dimers forming this motif are further linked by π–π interactions. With respective average deviations from planarity of 0.004 (2) and 0.004 (1) Å, the pyrazino[2,3-β]indolizine and cyano fragment are oriented at 0.8 (1)° to each other. The mean planes of the pyrazino[2,3-b]indolizine skeleton either lie parallel or are inclined at an angle of 28.7 (2)° in the crystal.
