3-(2,4-Difluorophenyl)-1-(pyridin-4-yl)benzo[4,5]imidazo[1,2- d ][1,2,4]triazin-4(3 H )-one

Abstract

In the title compound, C 20 H 11 F 2 N 5 O, the central 13-membered ring system (r.m.s. deviation = 0.028 Å) makes a dihedral angle of 53.13 (7)° with the difluorophenyl ring and 79.98 (7)° with the pyridine ring. The crystal packing features aromatic π–π interactions between the 13-membered rings [shortest distance between ring centroids = 3.5682 (8) Å].
