Abstract: In the title structure, [Ti2(C16H16N2O2)2O2]·2CHCl3, the Ti atom is coordinated in a distorted octa­hedral geometry by the O,N,N',O' donor set of the salalen ligand and by two [mu]2-oxide O atoms, which bridge two Ti(salalen) fragments into a centrosymmetric dimeric unit. In the central Ti2([mu]2-O)2 fragment, the metal-oxygen distances are significantly different [1.7962 (19) and 1.9292 (19) Å]. In the crystal, the chloro­form mol­ecule is anchored via an N-H...Cl and a bifurcated C-H...(O,O) hydrogen bond. Slipped [pi]-[pi] stacking [shortest C...C distance = 3.585 (4) Å] and C-H...[pi] inter­actions contribute to the coherence of the structure.
