title: A Planar Ti2P2Core Assembled by Reductive Decarbonylation of-O-C≡P and P-P Radical Coupling.
abstract: The complex [(nacnac)Ti(OAr)]2(μ2:η2,η2-P2) (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 P2complex and its structure reveals the rhombic Ti2P2core 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 Ti2P2core as well as the origin of the highly downfield31P NMR spectroscopic signal.
