(E)-2-Cyano-3-(2,3-dimeth­oxy­phen­yl)acrylic acid

The asymmetric unit of the title compound, C(12)H(11)NO(4), contains two mol­ecules. In the crystal, neighbouring mol­ecules are linked together by O—H⋯O hydrogen bonds into dimers. The dimers are arranged into columns parallel to the a axis, meditated by π–π inter­actions [centroid–centroid distanc...

Descripción
Sumario:The asymmetric unit of the title compound, C(12)H(11)NO(4), contains two mol­ecules. In the crystal, neighbouring mol­ecules are linked together by O—H⋯O hydrogen bonds into dimers. The dimers are arranged into columns parallel to the a axis, meditated by π–π inter­actions [centroid–centroid distances = 3.856 (3) and 3.857 (3) Å]. The crystal structure is further stabilized by weak inter­molecular C—H⋯O inter­actions. The crystal studied was a non-merohedral twin with a ratio of the twin components of 0.657 (11):0.343 (11).
