| Abstract: | Reaction of U(TrenTIPS)(THF)]BPh4] ( 1 ; TrenTIPS=N{CH2CH2NSi(iPr)3}3) with NaPH2 afforded the novel f‐block terminal parent phosphide complex U(TrenTIPS)(PH2)] ( 2 ; U–P=2.883(2) Å). Treatment of 2 with one equivalent of KCH2C6H5 and two equivalents of benzo‐15‐crown‐5 ether (B15C5) afforded the unprecedented metal‐stabilized terminal parent phosphinidene complex U(TrenTIPS)(PH)]K(B15C5)2] ( 4 ; U?P=2.613(2) Å). DFT calculations reveal a polarized‐covalent U?P bond with a Mayer bond order of 1.92. |
