Solvothermal synthesis and characterization of two high-nuclearity mixed-valent manganese phosphonate clusters. Academic Article uri icon


  • Two novel mixed-valent manganese (Mn(II)/Mn(III)) cluster compounds were synthesized in solvothermal reactions and characterized by single-crystal X-ray diffraction, bond valence sum calculations, IR spectra, elemental analysis, and magnetic measurements. Compound 1 is a Mn 19 cluster with a cylindrical core structure. Compound 2 possess a Mn 16 core where all of the manganese sites have unique ligation environments. The magnetic measurements on both compounds indicate dominant antiferromagnetic interactions between the metal centers.
