Beschreibungen/Notizen

• 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. Straightforward deprotonation of the first f‐block terminal parent phosphide complex and potassium ion results in the isolation of an unprecedented structurally authenticated metal‐stabilized terminal parent phosphinidene complex. B15C5=benzo‐15‐crown‐5 ether.
