Ethyl 2-[(E)-({2,4-dimethoxy-6-[2-(4-methoxyphenyl)ethenyl]benzylidene}amino)oxy]acetate

Abstract

In the title compound, C22H25NO6, the C=C double bond linking the benzene rings adopts an E configuration and the dihedral angle between the rings is 47.1 (2)°. The oxime unit contains a C=N double bond, which also has an E configuration. In the crystal, pairs of C—H...N hydrogen bonds generate inversion dimers and weak C—H...O interactions link the dimers into chains propagating along the b-axis direction.
