“…Coordination polymers (CPs) have garnered significant interest in crystal chemistry and materials science due to their intriguing structures and potential applications in various fields. These include catalysis (Adamji et al, 2023;Suremann et al, 2023;Wu et al, 2023;Xu et al, 2022), adsorption and separation (Chen et al, 2023;Daglar et al, 2021;Keasler et al, 2023;Liang et al, 2023), fluorescence sensing (Halder et al, 2023;Li et al, 2023), magnetism (Castro et al, 2022;Dong et al, 2023;Weng et al, 2011;Xu et al, 2023), and so on (Biswas et al, 2021;Naskar et al, 2017;Paul et al, 2017). The development of these CPs is commonly recognised to be predominantly influenced by the characteristics of the organic building blocks, the coordination geometry of the inorganic metal nodes and several synthetic parameters (Batten et al, 2016;Han et al, 2014;Rosa et al, 2016).…”

Reacting trimesic acid (H3TMA, C9H6O6) with CaCl2 and MCl2 at 110 °C under hydrothermal conditions gave the isostructural heterobimetallic coordination polymers (CPs) catena-poly[[tetraaquazinc(II)]-μ-5-carboxybenzene-1,3-dicarboxylato-[tetraaquacalcium(II)]-μ-5-carboxybenzene-1,3-dicarboxylato], [CaZn(HTMA)2(H2O)8] n , 1, and catena-poly[[tetraaquacobalt(II)]-μ-5-carboxybenzene-1,3-dicarboxylato-[tetraaquacalcium(II)]-μ-5-carboxybenzene-1,3-dicarboxylato], [CaCo(HTMA)2(H2O)8] n , 2. Compounds 1 and 2 crystallize in the monoclinic space group C2/c. The solid-state structures consist of eight-coordinate CaII ions and six-coordinate M II ions. These ions are connected by a doubly deprotonated HTMA2− ligand to create a one-dimensional (1D) zigzag chain. Poly[[decaaquabis(μ3-benzene-1,3,5-tricarboxylato)calcium(II)dizinc(II)] dihydrate], {[CaZn2(TMA)2(H2O)10]·2H2O} n , 3, was found incidentally as a minor by-product during the synthesis of 1 at a temperature of 140 °C. It forms crystals in the orthorhombic space group Ccce. The structure of 3 consists of a two-dimensional (2D) layer composed of [Zn(TMA)] chains that are interconnected by CaII ions. The presence of aromatic carboxylic acid ligands and water molecules, which can form numerous hydrogen bonds and π–π interactions, increases the stability of the three-dimensional (3D) supramolecular architecture of these CPs. Compounds 1 and 2 exhibit thermal stability up to 420 °C, as indicated by the thermogravimetric analysis (TGA) curves. The powder X-ray diffraction (PXRD) data reveal the formation of unidentified phases in methanol and dimethyl sulfoxide, while 1 exhibits chemical stability in a wide range of solvents. The luminescence properties of 1 dispersed in various low molecular weight organic solvents was also examined. The results demonstrate excellent selectivity, sensitivity and recyclability for detecting acetone molecules in aqueous media. Additionally, a possible sensing mechanism is also outlined.

It is still challenging for Dy-MOFs to modulate the single-molecule magnet (SMM) behavior through guest molecules. Dy-MOFs with different guest molecules, secondary building units, and linkers were synthesized by precursors and bridging carboxylic acid ligands, and the magnetic properties of Dy-MOFs were regulated by guest molecules. These differentiated Dy-MOFs are [Dy 2). The single-crystal X-ray diffraction showed that MOF-3 and MOF-5 are two-dimensional MOFs with square holes. MOF-4 is a two-dimensional MOF formed by hydrogen−halogen bonds, and MOF-6, MOF-7, and MOF-8 are one-dimensional chains. The magnetic test results show that MOF-4, MOF-6, and MOF-8 show SMM behavior under zero field, and MOF-3 and MOF-5 exhibit field-induced SMM behavior. In the zero field, the effective energy bases of MOF-4, MOF-6, and MOF-8 are 37.09, 19.56, and 15.73 K, and relaxation times τ 0 were 4.66 × 10 −6 , 2.35 × 10 −6 , and 9.95 × 10 −6 s, respectively. This work provides a vivid example of regulating the molecular magnetism of Dy-MOFs and promotes the progress of Dy-MOF crystal engineering.
