Direct observation of electron localisation in a mixed-valence double salt: a polarised neutron diffraction study of K3(MnO4)2
Abstract
A polarised neutron diffraction study of the compound K3(MnO4)2 shows strong localisation of the unpaired electrons on half of the manganese sites, confirming the formulation as a mixed-valence double salt K3[MnVIIO4][MnVIO4].
