Herein, we report the first example of a planar tetranuclear uranium hydride cluster [(CpCMe<jats:sub>2<\/jats:sub>CMe<jats:sub>2<\/jats:sub>Cp)U]<jats:sub>4<\/jats:sub>(<jats:italic>\u03bc<\/jats:italic><jats:sub>2<\/jats:sub>\u2010H)<jats:sub>4<\/jats:sub>(<jats:italic>\u03bc<\/jats:italic><jats:sub>3<\/jats:sub>\u2010H)<jats:sub>4<\/jats:sub> (U<jats:sub>4<\/jats:sub>H<jats:sub>8<\/jats:sub>). It was synthesized by reacting an <jats:italic>ansa<\/jats:italic>\u2010bis(cyclopentadienyl) ligand\u2010supported uranium chloride precursor [(CpCMe<jats:sub>2<\/jats:sub>CMe<jats:sub>2<\/jats:sub>Cp)U]<jats:sub>3<\/jats:sub>(<jats:italic>\u03bc<\/jats:italic><jats:sub>2<\/jats:sub>\u2010Cl)<jats:sub>3<\/jats:sub>(<jats:italic>\u03bc<\/jats:italic><jats:sub>3<\/jats:sub>\u2010Cl)<jats:sub>2<\/jats:sub> with NaHBEt<jats:sub>3<\/jats:sub>. The presence of hydrides in U<jats:sub>4<\/jats:sub>H<jats:sub>8<\/jats:sub> was confirmed by NMR spectroscopy and its reactivity with phenol and carbon tetrachloride. DFT calculations also facilitated the determination of the hydrides\u2019 positions in U<jats:sub>4<\/jats:sub>H<jats:sub>8<\/jats:sub>, featuring four bridging <jats:italic>\u03bc<\/jats:italic><jats:sub>2<\/jats:sub>\u2010H ligands and four face\u2010capping <jats:italic>\u03bc<\/jats:italic><jats:sub>3<\/jats:sub>\u2010H ligands, with the four U centers arranged in a rhombic geometry. The U<jats:sub>4<\/jats:sub>H<jats:sub>8<\/jats:sub> represents not only the first example of planar polynuclear actinide metal hydride cluster but also the uranium hydride cluster with the highest
