The crystal structure of the title compound, C19 H17F3 N2O4, a metabolite of the fungicide trifloxystrobin (TFS), contains one molecule in the asymmetric unit. The CF3 group is disordered over two positions. The important characteristics of the molecule are the two C=N bonds in an E,E configuration, one in the -methoxy system and the other in the oxymethyl side chain between the two aromatic rings. The molecules are linked via an O-HN hydrogen bond and an infinite spiral is formed along the b-axis direction.
