The syntheses and physicochemical properties of the three dinitrogen complexes [Mo(N 2 ) 2 (tdppme)(PMe 3 )], [Mo(N 2 )(tdppme)(PMe 3 ) 2 ] and [Mo(N 2 ) 2 (tdppme)(PMe 2 Ph)] supported by the tripodal ligand 1,1,1‐tris(diphenylphosphinomethyl)ethane (tdppme) are reported. The complexes are characterized by 31 P NMR‐, IR‐ and Raman spectroscopy. The influence of the ligand tdppme on the coordination of PMe 3 , PMe 2 Ph, PMePh 2 , PPh 3 and dcpm (bis(dicyclohexylphosphine) is investigated and compared to earlier results involving dppm and dmpm as co‐ligands.
