(E,E)-α-(Methoxy­imino)-2-[({1-[3-(tri­fluoro­methyl)­phenyl]­ethylidene}amino)­oxy­methyl]­benzene­acetic acid

The crystal structure of the title compound, C₁₉H₁₇F₃N₂O₄, 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 β-methoxy system and the other in the oxy­methyl side chain between the two aromatic rings. The mol­ecules are linked via an O—H...N hydrogen bond and an infinite spiral is formed along the b-axis direction.

Methyl (Z,E)-α-(methoxy­imino)-2-[({1-[3-(tri­fluoro­methyl)­phenyl]­ethyl­idene}­amino)­oxy­methyl]benzene­acetate

The title compound, C₂₀H₁₉F₃N₂O₄, crystallizes with two mol­ecules in the asymmetric unit. The important characteristics of the mol­ecule are the two C=N bonds in Z,E configuration, one in the β-methoxy-system and the other in the oxy­methyl side chain between the two aromatic rings.
