Invariant nature of substituted element in metal-hexacyanoferrate.

ABSTRACT: The chemical substitution of a transition metal (M) is an effective method to improve the functionality of materials. In order to design the highly functional materials, we first have to know the local structure and electronic state around the substituted element. Here, we systematically investigated the local structure and electronic state of the host (M _h) and guest (M _g) transition metals in metal-hexacyanoferrate (M-HCF), Na _x (M _h, M _g)[Fe(CN)₆] _y (1.40 < x < 1.60 and 0.85 < y < 0.90), by means of extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) analyses. The EXAFS and XANES analyses revealed that the local structure and electronic state around M _g a
