Reaction of rhodium trichloride and dirhodium(II) acetate with trans-4,4′-bis(diethoxyphosphoryl)biphenyl-18-crown-6
摘要:
The complexation of RhCl3 center dot 3H(2)O and [RH2(CH3COO)(4)center dot 2H(2)O] with trans-4,4'-bis (diethoxyphosphoryl)biphenyl-18-crown-6 in various media was studied. In the synthesized compounds the rhodium(III) or dirodium(II) ions form supramolecular ensembles with ligand environment. The compounds were characterized by NMR, IR, Raman, ESR, X-ray electron spectroscopy, conductivity, and the data of elemental and X-ray fluorescence analyses. The predominant role of diethoxyphosphoryl groups at the macrocycle in binding rhodium(III) and dirhodium(II) ions was demonstrated.
