Polynuclear complexes constructed by lanthanides and pyridine-3,5-dicarboxylate ligand: Structures, thermal and luminescent properties

Spectroscopic (IR, Raman) and thermogravimetric studies of 3d-metal cinchomeronates and dinicotinates

“…The study of metal complexes with nicotinic acid and cinchomeronic acid has shown that these complexes can have different types of metal-ligand coordination [24][25][26]. Whitfield et al [24] studied the complexes of cobalt and nickel with 3,5-pyridinedicarboxylic acid.…”

“…However, in the nickel complex (NiLÁH 2 O), there are two types of bonds: monodentate and bidentate chelating. Łyszczek and Mazur studied the structures and thermal properties of lanthanide dinicotinates [25]. Studies have shown that the lanthanides form the types of coordination, such as monodentate, bidentate bridging and chelating bidentate.…”

Potentiometric determination of novel complexes of selected lanthanide ions with N,N’-bis(5-methylsalicylidene)-4-methyl-1,3-phenylenediamine

“…Aza-containing Schiff's base can be used as a neutral ion carrier of a highly selective Ln 3+ -PVC membrane electrode [18]. Lanthanide ions indicate high coordination numbers, variable, and flexible coordination environments [19,20]. Schiff-base salen-type ligands are very flexible compounds, and the combination of these species has great potential in the synthesis of novel and unusual coordination compounds of mononuclear [21,22], polynuclear [23] or polymer [24][25][26][27]-type complexes.…”

Coordination polymers of Na(I), Mg(II) and Co(II) ions based on biphenyl-4,4′-diacetic acid: Synthesis, crystal structures and thermal properties

“…These compounds are constructed by self-assembly of multidentate bridging ligands with metallic centers [13,14]. Polycarboxylic acids containing rigid moieties such as: benzene [15][16][17][18], pyridine [19][20][21], naphthalene [22][23][24] or biphenyl [25][26][27][28][29] are dominant building blocks in formation of coordination polymers. According to the rational design of coordination polymers, organic linkers can be modified through elongation or introduction of additional functional groups into the ligand structure.…”

“…As continuation of our efforts toward the construction of multidimensional coordination polymers with the rigid polycarboxylate ligands such as: 1,2,4-benzenetricarboxylic acid [39], pyridine-3,5-dicarboxylic acid [19,40] or biphenyl-4,4 0 -dicarboxylic acid [29,41], our recent study has been mainly focused on the synthesis and structural characterization of coordination polymers based on biphenyl-4,4 0 -diacetic [42] acid and some representative metal ions from s-(sodium(I) (1) and magnesium(II) (2)) and d-blocks (cobalt(II) (3)). Sodium and magnesium belongs to the same s-electron block metals, but their form entirely different coordination compounds with the same ligand as it can be seen from the analysis of known crystal structures of carboxylates [43].…”
