“…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.…”

“…A Teflon-lined vessel is placed in a steel autoclave, in which the reagents are heated in high-boiling polar solvents, such as DMF, DEF, DMSO, H 2 O, acetone, acetonitrile etc. The advantage of this method is that it ensures high solubility of the precursors and the formation of good quality MOF crystals suitable for structural investigations [46][47][48][49]. Among the nonsolvothermal methods of MOF synthesis, classical precipitation and mechanochemistry can be distinguished.…”

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.

“…Hence, the main aim of the present work was to synthesize new coordination polymers derived from p-XBTA by exploring different hydrothermal and reverse precipitation methods in aqueous medium. These methods could allow to cope with sparingly soluble ligands in water and to obtain pure crystalline products [10,11,12]. This study thus reports on the preparation, complete characterization, crystal structures, spectroscopic features, topological classification, and thermal behavior of two new polymeric 3D metal-organic architectures driven by flexible p-XBT 2− linkers.…”

Two new 3D coordination polymers (CPs), formulated as [Zn(p-XBT)]n (1H) and [Cd(p-XBT)]n (2H), were assembled from a virtually unexplored p-xylylene-bis(2-mercaptoacetic) acid linker (p-XBTA) and characterized by infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), thermal analysis methods (TG-DSC, TG-FTIR), single-crystal X-ray diffraction, and topological analysis. Two different synthetic strategies were explored, namely the precipitation (P) and hydrothermal (H) methods, resulting in a Zn(II) derivative [Zn(p-XBT)·H2O]n (1P) and its dehydrated analogue [Zn(p-XBT)]n (1H), respectively. In the Cd(II)-containing system, the same [Cd(p-XBT)]n (2P = 2H) products were generated by both synthetic methods. Upon dehydration, 1P undergoes a “crystal-to-crystal” phase transition in the 170−185 °C temperature range, producing an anhydrous polycrystalline sample (1H). Both CPs 1H and 2H are isostructural and feature polymeric 3D metal-organic nets of the cds topological type, which are driven by the 4-linked metal and p-XBT2− nodes. These compounds represent unique examples of coordination polymers derived from p-xylylene-bis(2-mercaptoacetic) acid, thus opening up the use of this flexible S,O-heterodonor building block in the design of polymeric metal-organic architectures.

Non‐centrosymmetric metal–organic frameworks (MOFs) have recently emerged as a promising class of coordination polymers for nonlinear optics and light conversion. Nevertheless, achieving high endurance and efficiency for the light conversion within the whole visible range by a single crystal of MOF remains a challenge. This article reports on the design of two non‐centrosymmetric MOFs based on a 1,3,5‐benzenetricarboxylic acid ligand and Er/Co ions, providing an efficient and simultaneous multiple second and third optical harmonic generations (SHG, THG) from 400 to 750 nm with a high endurance (over 100 cycles or 3 h of continuous operation). Optical experiments and quantum chemical modeling of the MOF single crystals confirm the polarization and chemistry‐dependent efficiency of SHG and THG, associated with the varied MOFs' symmetry and dipole moment. The observed coherent light conversion within the whole visible range by MOF single crystals at ambient conditions makes it possible to achieve the multicolor (up to three) coherent emission required for modern laser technologies, making MOFs highly competitive and sustainable materials for nonlinear optics.
