Crystal structure of (2E)-1-(1-benzo­furan-2-yl)-3-(2-bromo­phen­yl)prop-2-en-1-one monohydrate

The title compound, C(17)H(11)BrO(2)·H(2)O, crystallizes as a monohydrate in the chiral ortho­rhom­bic space group P2(1)2(1)2(1), and has non-linear optical (NLO) properties. The mol­ecule has an E conformation about the C=C bond and is relatively planar with the benzo­furan and bromo­phenyl rings being inclined to one another by 10.60 (14)°. In the crystal, the water mol­ecule is linked to the organic mol­ecule by O—H⋯O hydrogen bonds, forming an R (2) (2)(7) ring motif while C—H⋯O hydrogen bonds lead to the formation of helices along the b-axis direction.
