“…Additionally, another common synthetic strategy to obtain 3d/4f compounds consists of the use of a simple complex species acting as ligand; however this strategy is used less often to obtain extended networks. The work of Yao et al, reports that the use of a previously synthesized Co II precursor, [Co(3,5-pdc)(H 2 O) 5 ]·H 2 O (pdc = pyridine dicarboxylic acid) permits to generate extended networks. Thus, when the complex precursor of Co II is mixed with Gd III and La III under hydrothermal conditions a bidimensional network of [LnCo(pdc) 2 (Hpdc)(H 2 O) 7 ]·H 2 O (Ln = Gd III , La III ) can be obtained …”

Novel 3d/4f heterometallic three-dimensional (3D) networks, based on CoII/GdIII cations and imidazole-4,5-dicarboxylic acid (H3IDC) and oxalate which are acting as main and auxiliary ligand, respectively, were hydro-/solvothermally synthesized using different synthetic strategies. While [Gd(H2O)(C2O4)Co(IDC)(H2O)1.26(CH3CH2OH)0.74]·1.75H2O (1) was obtained in a one-pot synthesis, [Gd(H2O)Co(HIDC)(C2O4)1.5]·2.65H2O (2) was obtained using a CoII complex precursor. Both compounds crystallize in a monoclinic system within the centrosymmetric space group C2/c. These structures are characterized by presenting an intricate covalent 3D network. A notable aspect is the fact that in these centrosymmetric structures CoII(IDC/HIDC) moieties are disposed along the networks forming alternate chiral chains, Λ and Δ. From a magnetic point of view, both (1) and (2) have antiferromagnetic interactions, but in (1) a magnetic order appears below 8 K, probably as product of uncompensated antiferromagnetic interactions produced by centers with different spin values. This ferrimagnetic behavior was verified by the hysteresis curve at 1.8 K, and by well-defined maxima, both in the in-phase and out-of-phase ac susceptibilities curves. Remarkably, this work reports efficient synthetic methods through which it is possible to generate 3d/4f networks, these being scarce in the literature.

“…In addition, another common strategy reported for the synthesis of 3d/4f CPs is to use simple compounds as ligands; however, this strategy rarely yields multidimensional polymers. 29 From the point of view of polymer synthesis, it is meaningful to obtain 3d/4f two-dimensional CPs. For example, the degree of protonation of H 3 CAM ligands depends on the synthesis conditions, where the ligand is separated into HCAM 2− .…”

Reported here are the design and fluorescence characters of a Ni II /Tb III polymer, [Tb 2 Ni 3 (HCAM) 6 (H 2 O) 12 ] n ( 1 ) (H 3 CAM = chelidamic acid). Under physiological conditions, the binding of biocompatible water soluble 1 to human serum albumin (HSA) was studied by spectroscopy techniques, which revealed that 1 could inherent the fluorescent light of HSA in a static quencher course and change the HSA second-level structure. The marked enhancement in 1 and its fluorescence intensity provide conclusive evidence that 1 can play the role of a “turn-on” sensor for recognition and detection of HSA in other biological interferents with a K sv value of 7.68 × 10 4 M –1 and a detection limit of 0.14 μM. Luminescence experiments show that 1 has high selectivity and sensitivity to MnO 4 – in other anions. Its quenching efficiency ( K sv ) is 5.54 × 10 3 M –1 , and the detection limit is 0.29 μM.

“…The carboxylate groups of ligands act in different modes in metal ion coordination as a bidentate bridging, bidentate chelating, threedentate chelating-bridging or monodentate so the complexes can have different structures either polymeric, dimeric and monomeric. The synthesis and physico-chemical properties of pyridine derivative ligands are important because a diversity of coordinating structures can be formed, including solid coordination polymers and their numerous applications in material chemistry, catalysis, luminescence and magnetochemistry [7][8][9][10][11][12].…”

The lanthanide(III) complexes with 2,3-pyridinedicarboxylate ligand (PDC) were obtained as crystalline compounds from the water solutions. These compounds form the series of Ln 2 (PDC) 3 · nH 2 O. All compounds are stable in air and insoluble in both water and common organic solvents. The hydrated complexes have been characterized by elemental analysis, thermal analysis (TG/DSC/DTA, and TG−FT-IR), FT-IR spectroscopy and X-ray analysis. 2,3-pyridinedicarboxylates of lanthanides(III) are stable in air below 313−323 K. Upon heating, hydrated complexes lose crystallization and lattice water in two steps. The values of dehydration enthalpy complexes are calculated from the DSC curves. The anhydrous compounds are stable at the temperature from 473 K to about 623 K and when heated they decompose to lanthanide oxides. Thermal and spectroscopic studies are essential for further studies and classification of compounds as MOF-like structures.
