Reaction of [U(Tren TIPS )(THF)][BPh 4 ] ( 1 ; Tren TIPS =N{CH 2 CH 2 NSi( i Pr) 3 } 3 ) with NaPH 2 afforded the novel f‐block terminal parent phosphide complex [U(Tren TIPS )(PH 2 )] ( 2 ; U–P=2.883(2) Å). Treatment of 2 with one equivalent of KCH 2 C 6 H 5 and two equivalents of benzo‐15‐crown‐5 ether (B15C5) afforded the unprecedented metal‐stabilized terminal parent phosphinidene complex [U(Tren TIPS )(PH)][K(B15C5) 2 ] ( 4 ; UP=2.613(2) Å). DFT calculations reveal a polarized‐covalent UP bond with a Mayer bond order of 1.92.
