(E)-2-Hy-droxy-4-meth-oxy-3-(3-methyl-but-2-en-yl)-6-styryl-benzoic acid.


ABSTRACT: The title compound, C21H22O4, also known as cajanine, features an intra-molecular O-H?O hydrogen bond between the adjacent carb-oxy and hy-droxy groups. The benzene rings make an inter-planar angle of 175.4?(2)°. In the crystal, mol-ecules are linked by pairs of O-H?O hydrogen bonds, forming inversion dimers.
