Abstract: The title compound, C32H24Cl2O2·C3H6O, was synthesized by the dimerization of 2-(4-chlorobenzal)inden-1-one, induced by a low-valent titanium reagent (TiCl4/Zn). X-ray analysis reveals that the cyclopentane ring spiro-fused to the five-membered ring adopts an envelope conformation, while the other cyclopentane ring adopts an envelope conformation.
