Abstract:
The title compound, C17H11BrO2·H2O, crystallizes as a monohydrate in the chiral ortho-rhom-bic space group P212121, and has non-linear optical (NLO) properties. The mol-ecule has an E conformation about the C=C bond and is relatively planar with the benzo-furan and bromo-phenyl rings being inclined to one another by 10.60 (14)°. In the crystal, the water mol-ecule is linked to the organic mol-ecule 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.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
