2,2′-[(3-Bromo-4-hy­droxy-5-meth­oxy­phen­yl)methyl­idene]bis­(3-hy­droxy-5,5-dimethyl­cyclo­hex-2-en-1-one)

In the title compound, C(24)H(29)BrO(6), the dihedral angle between the cyclo­hexenone mean planes is 57.63 (2)° while the dihedral angles between the benzene ring and the cyclo­hexenone mean planes are 58.42 (2) and 69.08 (3)°. The two cyclo­hexenone rings both show an envelope conformation, with the C atom bearing two methyl groups as the flap atom in each ring. Two intra­molecular O—H⋯O hydrogen bonds occur. In the crystal, molecules are linked via pairs of O—H⋯O hydrogen bonds, forming inversion dimers.
