The structure of trichlorotris(tetrahydrofuran)titanium(III)

Crystal structure of (η 5-pentamethylcyclopentadienyl)titanium(III)dichloride (THF), C14H23Cl2OTi

“…The Ti1-O1 distance is with 2.0859(13) Å comparable to those in TiCl 3 (THF) 3 with about 2.09 Å, as well as the Ti1-Cl distances with 2.3426(2) Å respectively 2.3251(6) Å compared to ca. 2.3 Å [9]. The distance between titanium and the center of the vemembered ring (2.004 Å) is one of the shortest, found so far, compared to other Cp*Ti-complexes (Cp*TiCl 3 , 2.021 Å [10]; Cp* 2 TiH, 2.03 Å [11]; Cp*Ti(η 5 :η 1 -benzofulvene) 2.006 Å [12]).…”

Spectroscopic Investigation of Heterogeneous Ziegler–Natta Catalysts: Ti and Mg Chloride Tetrahydrofuranates, Their Interaction Compound, and the Role of the Activator

“…[24] For the [TiCl 3 A C H T U N G T R E N N U N G (thf) 3 ] complex, only one isomer has been reported in the literature, with octahedrally coordinated Ti III and meridional configuration of Cl atoms (Figure 2 b). [25] Coming to the Mg precursor, it has been reported that several crystalline MgCl 2 tetrahydrofuranates coexist in equilibrium in thf solvent: [26] …”

Topotactic reversible phase transition between room-temperature and a new low-temperature modification in the MCl3(THF)3 system

“…I ~*CI 004H8 The V complex VC13(THF) 3 [4] is isotypic to the Sc [2] and Cr [4] analogues but not to the Ti compound: The latter shows a closely related crystal structure with an approximately double lattice constant a and two independent and conformationally different molecules in the asymmetric unit [3].…”

“…The THF adducts of the trivalent early transition metal chlorides mer-MC13(THF) 3 (1) (M = Sc, Ti, V, Cr) are readily accessible [1] and their crystal and molecular structures have been determined by X-ray diffraction [2-4].…”
