The reaction of MoCl3(THF)3 with PhP(CH2CH2CH2PPh2)2 in THF/CH2Cl2 gave MoCl3(PhP(CH2CH2CH2PPh2)2) ·CH2CI2 (1). Sodium amalgam reduction of I in the presence of the monotertiary phosphines PMe3-nPhn (n = 0, 1, 2), in THF under nitrogen atmosphere, yielded the bis(dinitrogen) complexes

Mo(N2)2[PhP(CH2CH2CH2PPh2)2](PMe3) (2),

Mo(N2)2[PhP(CH2CH2CH2PPh2)2](PMe2Ph) (3), and

Mo(N2)2[PhP(CH2CH2CH2PPh2)2I(PMePh2) (4).

The homologous PPh3 and i-Pr3P derivatives as well as the attempted tris(dinitrogen) species Mo(N2)2[PhP(CH2CH2CH2PPh2)2] could not be isolated. Compounds 2-4 were assigned trans coordination of the N2 ligands on the basis of their IR, Raman, and 31P NMR spectra. The trans- octahedral geometry of these complexes was also confirmed by a single-crystal X-ray diffraction study performed on 3.

Keywords: Dinitrogen. Bis(3-diphenylphosphinopropvl)phenylphosphine. Molybdenum Complexes; 31P NMR Spectra; X -Ray; Determination
