We report the design, synthesis, and crystal structure of a conjugated aryleneethynyl molecule, 2-(2-4,5-dimethoxy-2-[2-(2,3,4-trifluorophenyl)ethynyl]phenyl}ethynyl)-6-[2-(pyridin-2-yl)ethynyl]pyridine, C30H17F3N2O2, that adopts a planar rhombus conformation in the solid state. The molecule crystallizes in the space group P, with Z = 2, and features two intramolecular sp2-C—H…N hydrogen bonds that
