The complexes [TiCl3(tmen){η1-OCH2CH(CH2) 3O}] 1, [Ti2(μ-Cl)2Cl4{η2-OCH 2CH(CH2)3O}2] 2 and [TiCl4(tmen)] 3 (tmen = Me2NCH2CH2NMe2) have been synthesized and structurally characterized by X-ray diffraction. The crystals of 1 consist of monomeric [TiCl3(tmen){η1-OCH2CH(CH2) 3O}] molecules. Three chloride, one oxygen and two nitrogen atoms form a distorted octahedron around the titanium atom. Compound 2 has a dimeric structure. Each titanium atom is surrounded by two bridging chloride atoms, two terminal chloride atoms and two oxygen atoms of the 2-tetrahydrofurfuryloxide ligand. The crystals of compound 3 consist of monomeric molecules in which four terminal chloride atoms and two nitrogen atoms from the chelate tmen ligand form a distorted octahedron around Ti. High catalytic activity was found for 1 and 2.
