Abstract

New heterobimetallic and trimetallic complexes of titanium, [Ti(η⁵-C₅H₅)₂(Cl)(μ-η¹:η⁶-RC₆H₄)Cr(CO)₃] (R = H(1), o-F (2), p-CH₃ (3), m-CH₃ (4), [Ti(η⁵-C₅H₅)₂(Cl)(μ-η¹:η⁶-C₆Me₅)CH₂)Cr(CO)₃}] (5), and [(μ-{Ti(η⁵-C₅H₅)₂ }){(η¹:η⁶-RC₆H₄)Cr(CO)₃}₂](R = H (6), p-CH₃ (7)), and gold, [Au(PPh₃)(μ-η¹:η⁶-RC₆H₄)Cr(CO)₃] (R = H (9), o-F (10)), were prepared by the addition of the transition-metal halide Ti(η⁵-C₅H₅)₂(Cl)₂ or Au{PPh₃}Cl to a tetrahydrofuran solution of the appropriate lithiated (π-arene)tricarbonylchromium(0) substrate. The characterization of the bi- and trinuclear products by analytical and NMR, IR, and mass spectral data is supported by X-ray studies of the fluorobenzene (2) and toluene (3) derivatives, which confirm that the phenyl ligand is π-coordinated to the chromium tricarbonyl group, as well as σ-bonded to the bent metallocene. Crystals of 2 were monoclinic, P2₁/n, with a = 10.431 (4) Å, b = 12.506 (13) Å, c = 13.905 (3) Å, β = 106.38 (2)°, and Z = 4. Crystals of 3 were orthorhombic, Pbca, with a = 14.138 (2) Å, b = 13.625 (2) Å, c = 19.229 (6) Å, and Z = 8.
