Novel Heterometallic Lanthanide Complex Using Cobalt Tripod Ligands: Synthesis, Crystal Structure Analysis, and Magnetic and Proton Conduction Behavior

Abstract

A 3d‐4f heterometallic cobalt(III)‐cerium(III) sandwich complex was successfully synthesized and its properties were analyzed. The structure of 1 was specifically analyzed by single crystal X‐ray diffraction analysis, and structural simulations were performed based on single crystal X‐ray diffraction data. We were able to observe changes in the structure of this complex accompanied by changes in proton conduction properties according to temperature and humidity conditions, indicating that the structure influences the formation of the proton conduction pathway. In addition, it was confirmed by measurement that this complex also exhibited magnetic behavior.

Design and synthesis of novel lanthanide MOFs by unique in situ organic and inorganic reactions

“…Due to their wide range of properties such as unique electronic structures and the lanthanide contraction effect among them, [1][2] metal-organic frameworks (MOFs) containing lanthanide ions (Ln 3+ ) have been extensively studied in recent research such as for luminescent sensors, 3 light converters, [4][5][6] magnetic materials, [7][8][9][10][11][12][13] and catalysis. [14][15] Furthermore, oxalate anions (C 2 O 4 2À ) have been mainly used for the synthesis of MOFs as a bridging ligand to construct various multidimensional MOFs.…”
