Mononuclear Molybdenum and Tungsten Phosphine Complexes for Catalytic Ammonia Synthesis: Development of the pentaPod Concept

ChemPhysChem, Volume 27, Issue 4, 25 February 2026.
The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt‐type complexes for N2‐to‐NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and,
