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 [mu]2-oxido bridges into a dinuclear centrosymmetric com­plex, with a Ti...Ti 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 [100], forming channels in which the solvent chloro­form mol­ecules are located. C-H...O hydrogen-bonding inter­actions between the complex mol­ecules and the solvent mol­ecules consolidate the crystal packing.
