Sulfur-substituted uranyl stabilized by fluoride ligands: matrix preparation of U(O)(S)F2via oxidation of U(0) by SOF2†
Abstract
A fluoride stabilized sulfur-substituted uranyl complex [U(O)(S)F2] was prepared for the first time via oxidation of U(0) by SOF2 in cryogenic matrixes. The electron withdrawing character of F in this neutral complex does not cause the oxidation of the sulfido ligand by U(VI), but increases the strength and covalency of the U–O and U–S bonds.
