The Palladium(IV)‐Centered Hexatungstate Ion [Pd$^{IV}$W$_6$O$_{24}$]$^{8−}$

We report on the synthesis of the palladium(IV)-containing hexatungstate [Pd$^{IV}$W$_6$O$_{24}$]$^{8−}$ (PdW$_6$) with a central 6-coordinated Pd$^{IV}$ ion, which is surrounded by a ring of six edge-shared WO$_6$ octahedra. The sodium salt of PdW6 was structurally characterized in the solid state by multiple techniques, and the solution redox chemistry was investigated by electrochemistry. The catalytic hydrogenation of o-xylene using supported PdW6 as a precatalyst was also studied.
