New bonds for the uranyl : The controlled conversion of an uranyl oxo group ([UO 2 ] + ) into covalently bonded UOH and UOSi groups is described for pentavalent uranyl Pacman complexes. The unusual oxo–hydroxy motif is achieved by a protonation reaction and retains the normally unstable U V uranyl oxidation state. This product is readily silylated by treatment with a chlorosilane resulting in UOSi bond formation (see scheme).
