摘要

The complex [(nacnac)Ti(OAr)]_2(μ~2 :η~2,η~2-P~2) (1) is formed via reductive decarbonylation of the phosphaethynolate ion ~-[OCP], which serves as a P atom source. Complex 1 is the first structurally characterized Group 4 transition metal P_2 complex and its structure reveals the rhombic Ti_2P_2 core is essentially planar with short bond lengths suggesting some degree of multiple bonding character between the Ti-P and P-P sites. Computational studies of 1 provide an understanding of the Ti_2P_2 core as well as the origin of the highly downfield 31P NMR spectroscopic signal.
