(2E,2'E)-1,1'-([1,1'-Biphen-yl]-4,4'-di-yl)bis-[3-(di-meth-yl-amino)-prop-2-en-1-one].

The title compound, C(22)H(24)N(2)O(2), crystallizes in space group P2(1)/n. The mol-ecular structure is almost planar except for a tilt of the phenyl rings. The allyl groups on both ends exhibit the trans-form and the connected N atoms show sp (2) character. The mol-ecules are stacked and assembled along the c-axis direction by C-H⋯π inter-actions.
