- Abstract
Although the cyclo-P6 complex [(Cp*Mo)2(μ,η6:η6-P6)] ( 1) was reported 30 years ago, little is known about its chemistry. Herein, we report a high-yielding synthesis of 1, the complex 2, which contains an unprecedented cyclo-P10 ligand, and the reactivity of 1 towards the 'naked' cations Cu+, Ag+, and Tl+. Besides the formation of the single oxidation products 3 a,b which have a bisallylic distorted cyclo-P6 middle deck, the [M( 1)2]+ complexes are described which show distorted square-planar (M=Cu( 4 a), Ag( 4 b)) 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.
