摘要
The Ce(III) anionic bis(pentalene) sandwich complex K[Ce{C8H4((SiPr3)-Pr-i-1,4)(2)}(2)] (1) has been prepared by treatment of CeCl3 with K-2[C8H4((SiPr3)-Pr-i-1,4)(2)] and crystallographically characterized as its 18-crown-6 complex. Oxidation of 1 with Ag[BPh4] affords the neutral, formally Ce(IV) sandwich complex [Ce{C8H4((SiPr3)-Pr-i-1,4)(2)}(2)] (2), whose molecular structure has also been determined. The electronic structure of 2 has been investigated in detail by a combination of magnetic studies, K-edge XANES measurements, gas-phase photoelectron spectroscopy, and density functional calculations.
