“…Furthermore, PDA displays strong size-based selectivity, owing to the formation of three rigid five-membered chelate rings upon complex formation. More precisely, PDA provides a fixed distance between the two potentially coordinating O-atom donors of the carboxylate groups (4.8 Å ), which requires large metal ions to fit into this cavity (Bencini & Lippolis, 2010;Ogden et al, 2013;Williams et al, 2009). Classification of the coordination modes found for PDA ligands in the CSD have been gathered (in Fig.…”

As an extension of our continued interest in the preparation of inorganic–organic hybrids, we report the successful hydrothermal synthesis of sodium tris[triaqua(μ‐1,10‐phenanthroline‐2,9‐dicarboxylato)dysprosium(III)] silicododecatungstate dodecahydrate, {[DyNa(C14H6N2O4)3(H2O)9(SiW12O40)]·12H2O}n or Na[Dy(PDA)(H2O)3]3[SiW12O40]·12H2O (1), and sodium aqua tris[tetraaqua(μ‐4‐hydroxypyridine‐2,6‐dicarboxylato)praseodymium(III)] silicododecatungstate dodecahydrate, {[NaPr(C7H3NO5)3(H2O)13(SiW12O40)]·12H2O}n or Na(H2O)[Pr(pydc‐OH)(H2O)4]3[SiW12O40]·12H2O (2) (in which H2PDA is 1,10‐phenanthroline‐2,9‐dicarboxylic acid and H2pydc‐OH is 4‐hydroxypyridine‐2,6‐dicarboxylic acid or chelidamic acid). Both compounds have been characterized using elemental analysis, IR spectroscopy and X‐ray diffraction methods. Structural characterization by single‐crystal X‐ray diffraction reveals that these compounds consist of [SiW12O40]4− Keggin‐type polyoxometalates (POMs), where a single {W3O13} triad is decorated with a trinuclear Ln complex. Moreover, the decorated polyanions are involved in a series of intermolecular interactions, such as hydrogen bonds and anion–π interactions, resulting in three‐dimensional supramolecular architectures. Density functional theory (DFT) studies were conducted to support these intermolecular interactions in both 1 and 2, and have been rationalized using molecular electrostatic potential (MEP) surface calculations.

“…5 It was shown that pyridindicarboxamides and dipiridyldicarboxamides are selective to actinides and can extract americium and curium from nitric acid solutions. 8,9 Thus, 1,10-phenanthroline-2,9-dicarboxylic acid was actively studied as a complexone for actinides [10][11][12][13] and also for d-elements. 6,7 Phenanthroline is a good basis for designing of preorganized ligands.…”

1,10-Phenanthroline-2,9-dicarboxamides as ligands for separation and sensing of hazardous metals

1,10-phenanthroline-2,9-dicarboxamides of various structure were synthesized and studied as ligands for separation and sensing of d-and f-metals. It was found that the extraction ability of dialkyl-diaryl-diamide to lanthanides decreases from La to Lu and extraction of Am is close to light lanthanides (La-Pr). Tetraalkyl-diamide are not selective to lanthanides, instead exhibiting moderate selectivity in Am/Ln separation. The diamide complexes with lanthanides and d-elements were synthesized and characterized by XRD analysis. All diamides have demonstrated good extraction ability to environmentally hazardous metals (cadmium, lead, copper). The synthesized compounds were also tested as ionophores in PVC-plasticized potentiometric sensor membranes. Such sensors displayed no perceptible response to lanthanides but exhibited high sensitivity towards copper, zinc, cadmium and lead. These compositions can be considered as promising cross-sensitive sensors for multisensor systems.

“…The diamides of H 2 PhenDA also exhibit excellent extraction of actinide ions and separation from lanthanide ions 16,17. To help understand the extraction behavior of the diamides, several thermodynamic and structural studies have been conducted on the coordination of H 2 PhenDA with actinide and lanthanide ions, including Ln III , Am III , Th IV , and U VI 18–21. However, there have been no studies on the complexation of Np V ions with these potentially tetradentate ligands.…”

Complexation of Np^V Ions with 1,10‐Phenanthroline‐2,9‐dicarboxylic Acid: Spectrophotometric and Microcalorimetric Studies

The complexation of Np V ions with a tetradentate ligand with oxygen and nitrogen donors, 1,10-phenanthroline-2,9dicarboxylic acid (denoted as H 2 L), was studied in aqueous solutions by spectrophotometric and calorimetric methods. Np V ions form a very strong 1:1 complex, NpO 2 L -, with the stability constant log β = 11.73 Ϯ 0.02 in 0.1 M NaClO 4 at 25°C. It is a much stronger complex than those of Np V ions with related ligands such as picolinic acid or dipicolinic acid,[a] Institute
