Streszczenie

Di-μ-chloro-tetrachlorobis(diethyl o-phthalate)dititanium(III) tetra(dichloromethane) was obtained by direct reaction of TiCl4, diethyl o-phthalate and metallic aluminum in CH2Cl2. The crystal structure was determined by X-ray diffraction methods and refined by a full-matrix least-squares technique to R = 0.0495 for 2026 independent non-zero reflections. Crystals are triclinic, space group Pl̄, with one complex molecule in the unit cell of dimensions: a = 10.475(8), b = 10.843(9), c = 11.190(12) Å, α = 76.91(8), β = 73.39(7), γ = 81.10(7)°. The crystals contain dimeric molecules possessing crystallographic symmetry centres. The titanium(III) ions are octahedrally coordinated by two terminal and two bridging chlorine atoms and two carbonyl oxygen atoms of diethyl o-phthalate. The magnetic susceptibility and ESR measurements revealed an antiferromagnetic exchange interaction between titanium atoms in the dimer.
