RESUMO
The title compound, C12H10N4O, comprises a central 1,2,3-triazole ring (r.m.s. deviation = 0.0030â Å) flanked by N-bound 4-cyano-phenyl and C-bound acetyl groups, which make dihedral angles of 54.64â (5) and 6.8â (3)° with the five-membered ring, indicating a twisted mol-ecule. In the crystal, the three-dimensional architecture is sustained by carbonyl-C=Oâ¯π(triazo-yl), cyano-C≡Nâ¯π(triazo-yl) (these inter-actions are shown to be attractive based on non-covalent inter-action plots) and π-π stacking inter-actions [inter-centroid separation = 3.9242â (9)â Å]. An analysis of the Hirshfeld surface shows the important contributions made by Hâ¯H (35.9%) and Nâ¯H (26.2%) contacts to the overall surface, as well as notable contributions by Oâ¯H (9.9%), Câ¯H (8.7%), Câ¯C (7.3%) and Câ¯N (7.2%) contacts.
