“…The acetic moieties are twisted away from the plane of the phenylene unit due to sp 3 hybridization of methylene carbon atoms. Some coordination polymers based on 1,2-phenylenediacetic ligand, often together with another rigid ligand, have been reported with transition metal ions [19][20][21][22][23][24]. To the best of our knowledge, there are only nine crystal structures of lanthanide coordination polymers that involve only this ligand as confirmed by the CSD [25] data search.…”

Solvothermal reactions of lanthanide (III) salts with 1,2-phenylenediacetic acid in N,N′-dimethylformamide (DMF) solvent lead to the formation of the metal complexes of the general formula Ln2(1,2-pda)3(DMF)2, where Ln(III) = Pr(1), Sm(2), Eu(3), Tb(4), Dy(5), and Er(6), 1,2-pda = [C6H4(CH2COO)2]2−. The compounds were characterized by elemental analysis, powder and single-crystal X-ray diffraction methods, thermal analysis methods (TG-DSC and TG-FTIR), infrared and luminescence spectroscopy. They exhibit structural similarity in the two groups (Pr, Sm, and Eu; Tb, Dy, and Er), which was reflected in their thermal behaviours and spectroscopic properties. Single-crystal X-ray diffraction studies reveal that Sm(2) and Eu(3) complexes form 2D coordination polymers with four crystallographically independent metal centers. Every second lanthanide ion is additionally coordinated by two DMF molecules. The 1,2-phenylenediacetate linker shows different denticity being: penta- and hexadentate while carboxylate groups exhibit bidentate-bridging, bidentate-chelating, and three-dentate bridging-chelating modes. The infrared spectra reflect divergence between these two groups of complexes. The complexes of lighter lanthanides contain in the structure coordinated DMF molecules, while in the structures of heavier complexes, DMF molecules appear in the inner and outer coordination sphere. Both carboxylate groups are deprotonated and engaged in the coordination of metal centers but in different ways in such groups of complexes. In the groups, the thermal decomposition of the isostructural complexes occurs similarly. Pyrolysis of complexes takes place with the formation of such gaseous products as DMF, carbon oxides, ortho-xylene, ethers, water, carboxylic acids, and esters. The complexes of Eu and Tb exhibit characteristic luminescence in the VIS region, while the erbium complex emits NIR wavelength.

“…Coordination polymers (CPs) are compounds that are formed by linking together inorganic metal nodes with organic linkers into polymeric structures that extend in one, two, or three dimensions [1,2]. The synthesis and structural characterisation of CPs has attracted considerable interest over recent years due to the diversity of the structures and their potential uses in applications such as adsorption, gas storage, separation and catalysis, especially when porous [3][4][5]. The structures of CPs are dictated by the nature of both the metal centres and the organic ligands, with the reaction conditions also playing an important role: the solvent, temperature and pH influence the product in many cases [6][7][8].…”

Three new divalent cadmium coordination polymers containing cyclohexyldicarboxylate and pillaring dipyridylamide ligands have been prepared and structurally characterized via single‐crystal X‐ray diffraction. All three compounds exhibited layered structures, but with different topologies and interpenetration schemes. [Cd2(12chedc)2(ebin)(H2O)2]n (1) [12chedc = 1,2‐cyclohex‐4‐ene‐dicarboxylate, ebin = ethylenediamine(bis)isonicotinamide] displays a 2D 3,4‐connected net with (426)(42638) topology, also known as the V2O5 structural type. {[Cd(13cdc)(ebin)]·H2O}n (2) (13cdc = cis‐1,3‐cyclohexanedicarboxylate) showed a rare 2D + 2D → 3D parallel polycatenated system of looped layer networks. {[Cd(13cdc)(hbn)]·H2O}n (3) [hbn = hexanediamine(bis)nicotinamide] manifests a (426)(42678) network, also known as the 3,5L2 net. All three materials were assayed as fluorescent “turn‐off” sensors for the detection of nitrobenzene in solution. Thermal decomposition behavior of the new phases is also discussed.
