title: Crystal structure of (E)-1,3-bis-(6-methoxy-naphthalen-2-yl)prop-2-en-1-one.
abstract: In the title compound, C25H20O3, the central -C(=O)-C=C- chain is disordered over two positions about the central C atom, with an occupancy ratio of 0.848 (6):0.152 (6). The mol-ecule is twisted with the two naphthalene ring systems being inclined to one another by 52.91 (9)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming a three-dimensional structure. The structure was refined as a two-component twin with a 180 ° rotation about the c* axis.
