“…Benzene multicarboxylate ligands are frequently applied in the construction of lanthanide(III) polymeric 1D, 2D and higher-dimensional frameworks. The exemplary compounds are lanthanide benzenedicarboxylates [11], benzene-1,3,5tricarboxylates [12], benzene-1,2,4,5-tetracarboxylates [13] and benzene-1,2,3,4,5,6-hexacarboxylates [14]. In each of the series of lanthanide complexes, one can observe two or three isostructural series indicating that the decreasing lanthanide ion radius has influence on the complex structure.…”

The metal-organic frameworks of the formula Ln(bta)ÁnH 2 O where n = 3, 4, 5 or 6; bta = benzene-1,3,5triacetate ion: [C 9 H 9 (COO) 3 ] 3-; Ln = La(III), Nd(III), Eu(III), Tb(III), Ho(III), Tm(III), Lu(III) were synthesized by the reaction of LnCl 3 ÁxH 2 O with ammonium salt of H 3 bta acid in water solution. Insoluble water compounds crystallize in the monoclinic or triclinic crystal system, and they are stable up to 30°C. When heated, they decompose up to 160-200°C in two stages to stable anhydrous compounds. The dehydrated compounds Ln(bta) are still crystalline and stable up to about 350°C. When heated above 350°C, they undergo decomposition where the intermediate products are Ln 2 O 2 CO 3 or Tb 4 O 6 CO 3 and the residues are: Ln 2 O 3 or Tb 4 O 7. The interpretation of IR spectra of title compounds was made taking into consideration the experimental and theoretical wavenumbers obtained for H 3 bta specie. The XPS spectra of H 3 bta and its complexes were recorded. The way of metal-carboxylate group of ligand coordination was discussed. This work presents the results of the XPS analyses, which allowed to determine the binding energies (E b) for the main lines of Ln3d, Ln4d, Ln5p, C1s, O1s spectra, spin-orbital splitting and full width at half maximum complexes.

“…On the other hand, new very diagnostic bands from the carboxylate groups are observed on the spectra of all complexes which is indicative of deprotonation of COOH groups and metal ions coordination. In the spectra of isomorphous complexes (Eu, Tb and Er), asymmetric and symmetric stretching vibrations of carboxylate groups appear in the ranges: 1597-1579 and 1359-1348 cm −1 , respectively [56][57][58][59][60][61][62][63][64]. A very similar position of bands derived from stretching vibrations of carboxylate groups suggests the same coordination modes of COO groups in the Eu, Tb and Er complexes.…”

“…This publication is continuation of our long-term research on coordination polymers of lanthanides with polycarboxylic acids [37,38,[47][48][49][50][56][57][58][59][60][61][62][63][64]. Herein, the influence of different synthetic approaches on structural and thermal properties of the coordination polymers based on the selected lanthanide(III) ions such as: Nd(III), Eu(III), Tb(III) and Er(III) as well as 1H-pyrazole-3,5-dicarboxylic acid (H 3 pdca) is studied.…”

The impact of different synthetic procedures such as: hydrothermal, mechanochemical and precipitation on the structure and thermal properties of coordination polymers of 1H-pyrazole-3,5-dicarboxylic acid (H3pdca) with selected lanthanide ions was determined. The prepared complexes of the general formula: Ln2(Hpdca)3⋅nH2O, where Ln = Eu(III), Nd(III), Tb(III) and Er(III); n = 6 or 7 were fully investigated by: elemental analysis, Energy-Dispersive X-Ray (ED-XRF) and infrared (ATR-FTIR) spectroscopy, powder as well as single-crystal X-ray diffraction methods and thermal analysis (TG-DSC and TG-FTIR) in various atmospheres. It was proved that all used strategies offer high yields of reactions along with crystallinity of the obtained products. The X-ray diffraction methods allowed to conclude that the complexes with the same metal ions exhibit the same crystal structure despite different synthesis routes. On the other hand, the coordination polymers of Eu(III), Tb(III) and Er(III) prepared under different conditions are isomorphous. Only neodymium(III) compounds have a different crystal structure. Thermal stability of the produced complexes was correlated with the synthesis conditions, in particular with the way of energy supply. It was found that the highest thermal stability was exhibited by the complexes prepared under the hydrothermal conditions. Additionally, based on the volatile products of metal complexes decomposition, the mechanism of their pyrolysis was proposed in relation to their structures.

A series of 4f–5f heteronuclear metallic complexes were synthesized by a hydrothermal route from mixtures of uranyl acetate, lanthanide nitrate, and 1,2,4,5‐benzenetetracarboxylic acid (H4BTA) in an aqueous system. Single‐crystal X‐ray analysis revealed that the thirteen UO2‐Ln‐BTA complexes ([(UO2)1.5Ln(C10O8H2)1.5(H2O)x]⋅y H2O; Ln=La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8), Dy (9), Ho (10), Er (11), Tm (12), Yb (13); x=6 for 1–4, x=5 for 5–13; y=0 for 4, y=1 for 3, y=2 for 2, y=3 for 5, 9, 10, 12, 13, y=4 for 1, 6, 7, 8, 11) are isomorphous with three‐dimensional structures. For the purpose of developing potential applications of the UO2‐Ln‐BTA complexes, we investigated their surface photovoltage and photocatalytic properties. In addition, the thermogravimetric analysis and photoluminescent properties of these complexes were also studied in detail.
