Crystal structure and Hirshfeld surface analysis of 7-eth-oxy-5-methyl-2-(pyridin-3-yl)-11,12-di-hydro-5,11-methano-[1,2,4]triazolo[1,5-c][1,3,5]benzoxadiazo-cine.


ABSTRACT: The title compound, C19H19N5O2, was prepared by the reaction of 3-amino-5-(pyridin-3-yl)-1,2,4-triazole with acetone and 2-hy-droxy-3-eth-oxy-benzaldehyde. It crystallizes from ethanol in a tetra-gonal space group, with one mol-ecule in the asymmetric unit. The 1,2,4-triazole five-membered ring is planar (maximum deviation = 0.0028?Å). The pyridine and phenyl rings are also planar with maximum deviations of 0.0091 and 0.0094?Å, respectively. In the crystal, N-H?N hydrogen bonds link the mol-ecules into supra-molecular chains propagating along the c-axis direction. Hirshfeld surface analysis and two-dimensional fingerprint plots have been used to analyse the inter-molecular inter-actions present in the crystal.
