trans-1,2-Bis(4-pyridyl)ethylene（Cat No.:R070178）is an organic compound composed of two pyridine rings connected by a trans-ethylene (–CH=CH–) bridge at the 4-position of each ring. With the molecular formula C12H10N2, it is a rigid, planar molecule commonly used in supramolecular chemistry and crystal engineering. Its ability to coordinate metal ions through the nitrogen atoms makes it an excellent bidentate ligand in coordination complexes. It also serves as a building block in the design of metal-organic frameworks (MOFs), host–guest systems, and photonic materials due to its conjugated structure and predictable geometry.
