Crystal structure and Hirshfeld surface analysis of 7-ethoxy-5-methyl-2-(pyridin-3-yl)-11, 12-dihydro-5, 11-methano [1, 2, 4] triazolo [1, 5-c][1, 3, 5] benzoxadiazocine. Acta Crystallographica Section E: Crystallographic Communications, 74(3), 367-370.
The title compound, Ci(9)H(19)N(5)O(2), was prepared by the reaction of 3-amino-5(pyridin-3-yl)-1,2,4-triazole with acetone and 2-hydroxy-3-ethoxybenzaldehyde. It crystallizes from ethanol in a tetragonal space group, with one molecule in the asymmetric unit. The 1,2,4-triazole five-membered ring is planar (maximum deviation = 0.0028 angstrom). The pyridine and phenyl rings are also planar with maximum deviations of 0.0091 and 0.0094 angstrom, respectively. In the crystal, N-H center dot center dot center dot N hydrogen bonds link the molecules into supramolecular chains propagating along the c-axis direction. Hirshfeld surface analysis and twodimensional fingerprint plots have been used to analyse the intermolecular interactions present in the crystal.
