The title compound, C 21 H 22 O 5 , a derivative of the antioxidant, anti-inflammatory compound curcumin, crystallizes with two molecules (A and B) in the asymmetric unit. The mean planes of the two 3,4-dimethoxyphenyl groups in A and B make dihedral angles of 57.9 (7) and 33.4 (3) . An extensive ne
In the title cocrystal, 0.972(C 18 H 19 NO 4 ).0.028(C 17 H 16 BrNO 3 ), which arose from an impure starting material, all the atoms are overlapped except for one OMe group and the Br atom. The dihedral angle between the benzene ring mean planes is 18.20 (13) . A weak N-HΓ Γ ΓO hydrogen bond helps t
