有機溶媒を用いたシアノ架橋FeLn配位高分子（Ln＝希土類）の高収率合成と熱分解挙動

摘要

The heteronuclear Ln[Fe(CN)_6] centre dot nH_2O (Ln=La, Gd, and Lu) complexes were synthesized by the mixing of (NH_4)_3[Fe(CN)_6] and Ln(NO_3)_3 in methanol. Although the yield of the Ln[Fe(CN)_6] centre dot nH_2O complexes was ca. 20 percent for well-known method in water solution, it improved to ca. 90 percent using this method. The calculated n values using TGA were 6 approx 7,4,4 for Ln=La, Gd, and Lu, respectively. LnFeO_3 single phase was obtained by the thermal decomposition of synthesized heteronuclear complexes.
