  • Title: Solvothermal synthesis and characterization of two high-nuclearity mixed-valent manganese phosphonate clusters.
    Author: Konar S, Clearfield A.
    Journal: Inorg Chem; 2008 May 05; 47(9):3489-91. PubMed ID: 18376822.
    Abstract:
    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.
