摘要：

An X-ray structural investigation establishes an unbridged Ti-Co bond in [(tC4H9O)3Ti-Co(CO)4] (1a) and shows it to crystallize in the orthorhombic space group Pbn2(1), with a = 1192.5(7) pm, b = 1375.8(9) pm, c = 1405.0(10) pm, and Z = 4. The variation of the alkoxide ligand leads to the more thermally unstable derivatives [(RO)3-TiCo(CO)4] (R = i-C3H7, CH(CF3)2, Ph), whereas trans-[(tC4H9O)3TiCo(CO)3(PPh3)] is formed in a elective axial carbon monoxide ligand substitution reaction between 1a and triphenylphosphine.
