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

摘要

In the title compound, C20H11F2N5O, the central 13-membered ring system (r.m.s. deviation = 0.028??) makes a dihedral angle of 53.13?(7)° with the di-fluoro-phenyl ring and 79.98?(7)° with the pyridine ring. The crystal packing features aromatic?π–π?inter-actions between the 13-membered rings [shortest distance between ring centroids = 3.5682?(8)??].
