| Outline of Final Research Achievements |
Introduction of bulky trialkoxyphenyl groups onto carboxlato bridging ligands of lanthanum-type ruthenium (II, III) dinuclear complexes gave rise to insufficient axial coordination of cyanido groups in combination with cyanido complexes. The bridging ligand was changed to amidato and formamidinato ions. The assembled complexes obtained using amidato ligands showed the ferrimagnetic ordering at low temperatures, though those with the formadinato ligand did not lead to the occurrence of the ferrimagnetic behavior because the dinuclear units became the low-spin state in the assembled complexes.

| Academic Significance and Societal Importance of the Research Achievements |
ランタン型ルテニウム(II,III)二核錯体は、第５周期元素の重い遷移金属（ルテニウム）から形成されているにも拘らず、低スピン状態に陥らず３個のスピンを有する稀有な磁性ユニットである。シアニド錯イオンとの組合せによる集積型磁性体の開発に於いて、二核内架橋配位子を、これまでのカルボン酸イオンからアミダートイオンあるいはホルムアミジナート配位子を用いても３次元集積構造が得られ、架橋配位子を変えることで集積化合物のスピン状態が制御できることが分かったことは意義深く、今後の二核ユニットを用いた磁気材料の開発に１つの指針を与えると考えられる。
