Abstract
The molecules of 2-benzoyl-1-benzofuran, C15H10O2,(I), interact through double C—H⋯ O hydrogen bonds, forming dimers that are further linked by C—H⋯ O, C—H⋯ π and π–π interactions, resulting in a three-dimensional supramolecular network. The dihedral angle between the benzoyl and benzofuran fragments in (I) is 46.15 (3)°. The molecules of bis (5- bromo-1-benzofuran-2-yl) ketone, C17H8Br2O3,(II), exhibit C2 symmetry, with the ...
