Insights into the Electronic Structure of a U(IV) Amido and U(V) Imido Complex
Reaction of the N‐heterocylic carbene ligand (i)PrIm (L(1)) and lithium bis(trimethylsilyl)amide (TMSA) as a base with UCl(4) resulted in U(IV) and U(V) complexes. Uranium's +V oxidation state in (HL(1))(2)[U(V)(TMSI)Cl(5)] (TMSI=trimethylsilylimido) (2) was confirmed by HERFD‐XANES measurement...

| description | Reaction of the N‐heterocylic carbene ligand (i)PrIm (L(1)) and lithium bis(trimethylsilyl)amide (TMSA) as a base with UCl(4) resulted in U(IV) and U(V) complexes. Uranium's +V oxidation state in (HL(1))(2)[U(V)(TMSI)Cl(5)] (TMSI=trimethylsilylimido) (2) was confirmed by HERFD‐XANES measurements. Solid state characterization by SC‐XRD and geometry optimisation of [U(IV)(L(1))(2)(TMSA)Cl(3)] (1) indicated a silylamido ligand mediated inverse trans influence (ITI). The ITI was examined regarding different metal oxidation states and was compared to transition metal analogues by theoretical calculations. |
