| Resumo | |
The title compound, C12H10N4O, comprises a central 1,2,3-triazole ring (r.m.s. deviation = 0.0030 angstrom) flanked by N-bound 4-cyanophenyl and C-bound acetyl groups, which make dihedral angles of 54.64 (5) and 6.8 (3)degrees with the fivemembered ring, indicating a twisted molecule. In the crystal, the threedimensional architecture is sustained by carbonyl-C=O center dot center dot center dot pi(triazoyl), cyano-C N center dot center dot center dot pi(triazoyl) (these interactions are shown to be attractive based on noncovalent interaction plots) and pi-pi stacking interactions [intercentroid separation = 3.9242 (9) angstrom]. An analysis of the Hirshfeld surface shows the important contributions made by H center dot center dot center dot H (35.9%) and N center dot center dot center dot H (26.2%) contacts to the overall surface, as well as notable contributions by O center dot center dot center dot H (9.9%), C center dot center dot center dot H (8.7%), C center dot center dot center dot C (7.3%) and C center dot center dot center dot N (7.2%) contacts.
