Unique uranium(III) cations anchored by polydentate sulfur-based ligands: Synthesis and structure of [U{ H(R)B(tim(Me))(2)}(2)(THF)(3)][BPh4] (R = H, Ph)
The reactions of bis(2-mercapto- 1 -methylimidazolyl)-borates ([H(R)B(tim(Me))(2)](-), R = H and Ph) with [UI3-(THF)(4)] and TI[BPh4] in tetrahydrofuran gave, in good yield, [U{H(R)B(tim(Me))(2)}(2)(THF)(3)][BPh4] (R = H (1), R = Ph (2)), Complexes I and 2 are rare examples of U(III)) cations and unprecedented examples of f elements anchored by sulfur-based polydentate ligands.
