Hirshfeld surface analysis and crystal structure of 7-methoxy-5-methyl-2-phenyl-11,12-dihydro-5,11-methano-1,2,4-triazolo[1,5- c ][1,3,5]benzoxadiazocine

The title compound, C 19 H 18 N 4 O 2 , crystallizes with two independent molecules in the asymmetric unit. The triazole ring is inclined to the benzene rings by 9.63 (13) and 87.37 (12)° in one molecule, and by 4.46 (13) and 86.15 (11)° in the other. In the crystal, classical N—H...N hydrogen bonds, weak C—H...O hydrogen bonds and weak C—H...π interactions link the molecules into a three-dimensional supramolecular network. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to investigate the intermolecular interactions present in the crystal, indicating that the most important contributions for the crystal packing are from H...H (51.4%), H...C/C...H (26.7%), H...O/O...H (8.9%) and H...N/N...H (8%) interactions.
