Polyoxometalates (POMs)-based lanthanide-oxo clusters (LnOCs) are a class of polynuclear lanthanide-oxygen complexes formed by polyoxometalates stabilization through oxygen bridge linkage, in which the POMs can be viewed as multi-dentate inorganic ligands. The POMs-based LnOCs have received a lot of attention because of their interesting structures and potential applications. In this paper, we summarize the classification, synthesis strategies, and properties of POMs-based LnOCs. Herein, the POMs-based LnOCs are classified into three main categories according to their metal core element types and quantities: pure 4f clusters, 5d-4f clusters, and 3d-4f clusters. Their synthetic strategies are grouped into four categories based on the source of the POMs involved in the structural assembly: lacunary POMs ligand-directed method, in-situ transformation of lacunary POMs ligand-directed method, in-situ generation of lacunary POMs ligand-directed method, and mixing multiple synthesis strategies. The single-molecule magnets and proton conductivity properties of POMs-based LnOCs are summarized.

“…The dimers of SSICG-4 are connected to each other and form a 2D layered structure, where NIPA acts as a bridge between two dimers (Figure 2c). Topological (with TOPOS 85−88 ) structure analysis revealed that the overall framework SSICG-4 has a network of two three-connected [Zn(II) and μ 3 -ATRZ ligand] nodes (Figure 2d) with (3,3-net), and the Schlafi symbol for this net is 4.8 2 . This heteronet can be classified as fes net according to the topos&RCSR.ttd database.…”

“…The scope of supramolecular self-assembly and the opportunity to fine-tune organic and inorganic components play a significant role in the preparation of important targeted structures. , In this context, coordination polymers (CPs) have gained significant attention as organic–inorganic hybrid crystalline materials due to the tunable factors associated with the self-assembly process during synthesis, such as solvent, temperature, metal-to-ligand ratio, coordinating modes of organic ligands, coordination geometries of metal centers, additive templating, etc . These properties open doors to explore a vast library of coordination polymers for investigation of a wide range of properties for selective applications.…”

Four new coordination polymers have been synthesized based on a mixed-ligand strategy, viz., ], SSICG-3; and [Zn 2 (ATRZ) 2 (NIPA)], SSICG-4 (4-ABPT = 3,5-di(pyridine-4-yl)-4H-1,2,4-triazol-4-amine, H 2 NIPA = 5-nitroisophthalic acid, and ATRZ = 3-amino-1,2,4-triazole, SSICG stands for the Solid State and Inorganic Chemistry Group at IIT Patna). The copper compounds are one-dimensional, whereas the nickel and zinc compounds are two-dimensional layer compounds. SSICG-3 possesses 4,4-net topology with a Schlafi symbol 4 4 .6 2 , whereas SSICG-4 exhibits a 3,3-net (fes) topology with a Schlafi symbol 4.8 2 . SSICG-1 and SSICG-3 have active metal sites due to the presence of replaceable coordinated water molecules and exhibits efficient catalytic activity for one-pot CO 2 cycloadditions. The conversions of SSICG-1 and SSICG-3 for CO 2 cycloaddition are 87 and 95% (turnover numbers (TON) of 174 and 190), respectively. The kinetic studies, substrate scope, recyclability, catalyst amount, and temperature dependence studies of the CO 2 cycloaddition reaction are discussed. These structurally diverse coordination polymers could contribute to broadening the scope of mixed-ligand coordination polymers for their applications in heterogeneous catalysis.

“…52 They can be built with most of the metals of the periodic table by using several organic linkers, and due to the inorganic/organic moieties, they feature more functionalities. 60,61 Silica-based nanostructured materials also have high surface areas, and, like MOFs, they can be tailored regarding porosity and organic pendant moieties by using different synthesis parameters in a simple and well-defined process (so-gel technology).…”
