Bathophenanthroline is a heterocyclic organic compound with the formula (C₆H₅)₂C₁₂H₆N₂. It is a derivative of 1,10-phenanthroline (C₁₂H₈N₂) with phenyl groups located at the 4 and 7 position. It is common bidentate ligand, forming a significant subset of transition metal complexes of 1,10-phenanthrolines. Many of these complexes have distinctive optical properties.^[2]^[3]
