New bonds for the uranyl: The controlled conversion of an uranyl oxo group ([UO2]+) into covalently bonded UO[BOND]H and UO[BOND]Si groups is described for pentavalent uranyl Pacman complexes. The unusual oxo–hydroxy motif is achieved by a protonation reaction and retains the normally unstable UV uranyl oxidation state. This product is readily silylated by treatment with a chlorosilane resulting in UO[BOND]Si bond formation (see scheme).
