Hirshfeld surface analysis and crystal structure of 7-meth-oxy-5-methyl-2-phenyl-11,12-di-hydro-5,11-methano-1,2,4-triazolo[1,5-c][1,3,5]benzoxadiazo-cine.

Abstract

The title compound, C19H18N4O2, crystallizes with two independent mol-ecules in the asymmetric unit. The triazole ring is inclined to the benzene rings by 9.63 (13) and 87.37 (12)° in one mol-ecule, 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 inter-actions link the mol-ecules into a three-dimensional supra-molecular network. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to investigate the inter-molecular inter-actions 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%) inter-actions.
