The title compound of 3-（2-chlorophenyl）-l,2-dihydrocyclobuta[c]benzo[f]quinoline was synthesized by the reaction of o-chlorobenzaldehyde, naphthalene-2-amine, and cyclobutanone in THF catalyzed by iodine. Its structure was determined by single crystal X-ray diffraction. The crystal is orthorhombic, space group Pna2 （1）, a = 0.758 4（2） nm, b=2.765 8（9） nm, c=0.730 5（2） nm, Mr=315.78, V=1.532 4（8） nm^3, Dc=1.369 g/cm^3, Z 4, /l（Mo Ko ）： 0. 247 mm^-1, F（000）= 656. The crystal structure of title compound C21 H15 C1N was solved by di- rect methods and refined by full-matrix least squares method to final R1：0. 037 3, wR2 =0. 082 7.
