Abstract

Reaction of the trivalent uranium complex [(((ArO)-Ar-Ad,Me)(3)N]U(DME)] with [Na(OCP)(dioxane)(2.5)] and 2.2.2 -crypt yields the mu-oxo-bridged, diuranium complex [Na(2.2.2-crypt)]-[{(((ArO)-Ar-Ad,Me)(3)N)U(DME)}(mu-O){(((ArO)-Ar-Ad,Me)(3)N)U(CP)}] (1). Complex 1 features an asymmetric, dinuclear U-IV-O-U-IV core structure with a cyaphide (CP-) anion eta(I)-CP bound to one of the U ions, and a kappa(2)-O DME coordinated to the other. The CP- ligand is unprecedented in uranium chemistry and is formed through reductive C-O bond cleavage of the phosphaethynolate anion (OCP-). An analogous reaction was performed starting from the tetravalent uranium halide complex [(((ArO)-Ar-Ad,Me)N-3)U(DME)(C1)]. This salt metathesis approach with 2.70 [Na(OCP)(dioxane)(2.5)] results in formation of the mononuclear complex [(((ArO)-Ar-Ad,Me)(3)N)U(DME) (OCP) (2) with an OCP- anion bound to the uranium(IV) center via the oxygen atom in an eta(1)-OCP fashion.
