In the title compound, [Ti2(C16H14N2O2)2O2]·2CHCl3, the TiIV atom in the centrosymmetric complex has a distorted octahedral N2O4 coordination environment and is linked via two 2-oxido bridges into a dinuclear centrosymmetric complex, with a TiTi separation of 2.7794 (8) Å. In the salen (N,N'-ethylenebis(salicylimine)) ligand, the two salicylimine units make a dihedral angle of 45.31 (5)°. The complex molecules are stacked parallel to , forming channels in which the solvent chloroform molecules are located. C-HO hydrogen-bonding interactions between the complex molecules and the solvent molecules consolidate the crystal packing.
