[RuH(CO)2(Cp)] reacts with [Ti(2,6-Me2C6H3O)(NMe2)3] (1) and [Ti(2,6-Me2C6H3O)2(NMe2)2] (2) to produce [(NMe2)2(2,6-Me2C6H3O)TiRu(CO)2(Cp)] (3) and [(NMe2)(2,6-Me2C6H3O)2TiRu(CO)2(Cp)] (4), respectively. Both products were characterized spectroscopically, and the structure of 4 was determined by an X-ray diffraction study. Compound 4 crystallizes in the space group P21/n with a = 8.201 (3) Å, b = 18.776 (4) Å, c = 16.739 (6) Å, β = 103.90 (3)°, and V = 2526.29 Å3. Full-matrix least-squares refinement converged at R = 5.6% and Rw= 6.5%. There is a direct, unbridged bond between titanium and ruthenium in 4, with a metal—metal bond length of 2.573 (1) A. Despite steric crowding in 4, this Ru—Ti distance is 0.09 A shorter than the Ru—Ti distance in [(NMe2)3TiRu(CO)2(Cp)], attributed in part to the weaker electron-donor ability of aryloxides.
