| Abstract: | Herein, we report the employment of the Mo? Mo quintuple bonded amidinate complex to stabilize Group 10 metal fragments {(Et3P)2M} (M=Pd, Pt) and give rise to the isolation of the unprecedented δ complexes. X‐ray analysis unambiguously revealed short contacts between Pd or Pt and two Mo atoms and a slight elongation of the Mo? Mo quintuple bond in these two compounds. Computational studies show donation of the Mo? Mo quintuple‐bond δ electrons to an empty σ orbital on Pd or Pt, and back‐donation from a filled Pd or Pt dπ orbital into the Mo? Mo δ* level (LUMO), consistent with the Dewar–Chatt–Duncanson model. |
