Construction and structural diversification of eight rare-earth MIII coordination complexes with 5-bromonicotinic acid N-oxide

This work presents eight rare-earth MIII complexes with 5-bromonicotinic acid N-oxide as the modular building block, which display various metallosupramolecular networks of 1-D chain and binuclear patterns, in virtue of the radii of distinct MIII ions and their coordination capability to N-oxide groups.82
