Although the cyclo-P-6 complex [(Cp*Mo)(2)(mu,eta(6):eta(6)-P-6)] (1) was reported 30years ago, little is known about its chemistry. Herein, we report a high-yielding synthesis of 1, the complex 2, which contains an unprecedented cyclo-P-10 ligand, and the reactivity of 1 towards the naked cations Cu+, Ag+, and Tl+. Besides the formation of the single oxidation products 3a,b which have a bisallylic distorted cyclo-P-6 middle deck, the [M(1)(2)](+) complexes are described which show distorted square-planar (M=Cu(4a), Ag(4b)) or distorted tetrahedral coordinated (M=Cu(5)) M+ cations. The choice of solvent enabled control over the reaction outcome for Cu+, as proved by powder XRD and supported by DFT calculations. The reaction with Tl+ affords a layered two-dimensional coordination network in the solid state.
