Abstract: The title compound, C32H20N2, was synthesized by the p-toluenesulfonic acid-assisted Schiff base reaction between 9-fluorenone and o-phenylenediamine. The molecule crystallizes in a centrosymmetric space group and is located on a twofold rotation axis. The two fluoren-9-ylidene moieties adopt a trans configuration as substituents on the linking benzene ring, making the entire molecule chiral.
