SYNTHESIS AND CRYSTAL-STRUCTURE DETERMINA TION OF DICHLORO-BIS[N-(TRIMETHYLSILYL)IMIDAZOL]DITITANIUM CHLOROFORM-(1 2)/

ichloro-bis[N-(trimethylsilyl)-imidazol]dititanium chloroform (1/2) 1 has been prepared by the reaction of titanium tetrachloride with N-tri methylsilylimidazole (NTMSI) in chloroform solution as orange crystals . The structure consists of two distorted TiCl5N octahedrons, which ar e connected by two chlorine atoms via common edges to a centrosymmetri c dimer [Ti2Cl8(NTMSI)(2)]. 2 CHCl3. The N-trimethylsilylimidazole lig ands each are located at one axial position of each octahedron, wherea s the equatorial positions are occupied by the chloro ligands. The res ults presented are discussed assuming a gradual formation of an 1:1 an d 1:2 adduct.
