Abstract

The reaction of the tetrametallic molecular loop [(CH₃CN)₆Mo₂(OOC-C₄H₆-COO)]₂[BF₄]₄ (1) (1 equiv.) with 2 equiv. of bis(diphenylphosphino)amine (dppa), 1,2-bis(diphenylphosphino)ethane (dppe) and bis(diphenylphosphino)methane (dppm) in propionitrile leads to the formation of the still tetrametallic complexes [(CH₃CH₂CN)₄(X)Mo₂(OOC-C₄H₆-COO)]₂[BF₄]₄ (X = dppa (2), dppe (3), dppm (4)), also displaying a loop structure. All three complexes are characterized by NMR spectroscopy (¹H, ¹¹B, ¹³C{¹H}, ¹⁹F, ³¹P{¹H}), IR spectroscopy, elemental analysis, TG-MS measurements and UV-vis spectroscopy, compounds 2 and 3 additionally by X-ray single crystal diffraction.
