DOI: 10.1039/C4DT02703E, PaperJorge H. Rodriguez, Christopher J. Ziegler
Hydrogen bonding of water molecules to Mn4O4 inner cubane of S = 19/2 Mn12 SMM gives rise to geometric and magnetic asymmetries. Two Mn ions hydrogen bonded to water molecules depart from their Mn4+(S = 3/2) states and acquire an incipient Mn3+(S = 4/2) character. The magnetic moment vectors of the cubane Mn ions are inequivalent.
