Hydrothermal Synthesis of Lanthanide and Lanthanide-Transition-Metal Cluster Organic Frameworks via Synergistic Coordination Strategy

The study of polynuclear lanthanide (Ln) complexes has been a field of rapid growth in coordination chemistry. Lanthanide clusters synthesized via a ligand-controlled hydrolytic approach using different flexible α-amino acids have been well summarized. In this chapter, we describe efforts to synthesize lanthanide and lanthanide-transition-metal (Ln-TM) cluster organic frameworks using rigid ligands of isonicotinic acid (HIN), 4-pyridin-4-ylbenzoic acid (HL), nicotinic acid (HNA), and 4-(3-pyridyl)benzoic acid (HL′) under hydrothermal condition. In addition, the synergistic coordination between these rigid ligands with other organic/inorganic ligands has also been discussed.
