Hydrothermal syntheses, structures, and magnetic properties of two new Mn(II) complexes with biphenyl-2,3,3′,5′-tetracarboxylic acid

Crystal structure of diaqua-bis(μ3-2-methyl-6-oxidopyridinium-4-carboxylato-κ3 O:O′:O′′)neodymium(III) chloride, C14H16ClN2O8Nd

“…The crystal engineering of supramolecular architectures based on metal and organic building blocks has been rapidly expanding in recent years owing to their novel and diverse topologies and potential applications [1,2]. Isonicotinic acid based ligands are very important building blocks to form …”

A new mixed-ligand Mn(II) coordination polymer: Protective and nursing values on renal calculus via reducing the Ca2+ concentration in urine

“…Recently, transition metal complexes containing inorganic metal ions and organic ligands have become the focus of interest due to not only their structural versatility but also their wide range of applications such as antitumor and antibacterial activities, insulin mimetic activities, luminescence properties, catalytic activities, magnetic properties, DNA binding properties, and gas adsorption. [1][2][3][4][5][6] It is well known that the structural versatility and activity properties of the metal-organic complexes are largely dependent on the choice of organic ligands and metal atoms used, as well as the reaction mechanism in which the complex is obtained. [7][8][9][10] Consequently, the logical design of the organic ligands and the selection of suitable metal ions play a key role in obtaining the coordination complexes with the desired properties.…”

Two unique lanthanide–organic frameworks based on biphenyl-2,3,3′,5′-tetracarboxylic acid: Syntheses, crystal structures and luminescence properties

“…In this article, we introduced H 4 bptc to construct lanthanide-organic frameworks under hydrolysis because it can provide different numbers of coordination sites for the formation of MOFs, which enhances the robustness of the resulting networks [8]. It can also produce various hydrogen bonding interactions depending on the extent of the hydrolysis and the deprotonation of the carboxylic acid [9,10]. Moreover, the freedom of the ligand to rotate is restricted when coordinated to the Ln(III) ions, and as a result the rigidity and aromaticity may increase the emission of the Ln(III) ions effectively [11,12].…”
