Crystal structure and characterization of a novel luminescent 2D metal-organic framework, poly[aquaitaconatocalcium(II)] possessing an open framework structure with hydrophobic channels

Hydrothermal syntheses, crystal structures, and photocatalytic properties of two Co(II) complexes with the flexible citraconic acid

“…The designs and selections of O‐donor and N‐donor ligands are important to the synthesis of coordination polymers with fascinating structures and excellent performances . Small aliphatic carboxylates are widely used as O‐donor ligands to obtain a number of coordination polymers not only for their low prices and good flexibilities, but also for their diverse coordination modes . Some time ago, we obtained several coordination polymers based on a flexible itaconic acid .…”

N‐donor‐induced Two Co(II) Coordination Polymers Derived from the Flexible Citraconic Acid as Photocatalysts for the Decomposition of Organic Dyes

“…The flexible ligands with at least one sp 3 -hybrid atom (generally C, N, O or S) in their backbones are often used to synthesize the coordination polymers because the flexible sections can twist or rotate around a single bond to meet the requirements of various metal-ligand coordination fashions. [17][18][19][20] Through the careful analysis of our and other researchers' previous work, it was found that the aliphatic carboxylates ligands (such as itaconic acid [21][22][23][24][25] and citraconic acid [26][27][28][29] ), had better flexibility than those aromatic carboxylic acids (for example, phenylacetate acid [30][31][32][33] and phenylpropionic acid). [34,35] Furthermore, the N-donor ligand is a very important component of adjusting the structures and flexibilities of coordination polymers to satisfy the requirement of coordination geometries of metal ions in the assembly process.…”
