“…And the bond length of Ni–N is longer than that of Co–N, i.e., the Ni–N bond possesses relative lower bond energy (Figure S1 and Table S2). Cui and Janiak also found that the bond energy of Co–N is larger than that of Ni–N when Ni 2+ and Co 2+ simultaneously coordinate with imidazole ring, − confirming that 2-MeIM prefers to coordinate with Co instead of Ni even under high feeding ratio of Ni to Co. In addition, the crystal structure of Ni-ZIF-67 was analyzed with powder X-ray diffraction.…”

Hollow porous carbon (HPC) composed of inner voids and outer shells, is receiving increasing attention in constructing supported catalysts for diverse applications. It is of great allure but still challenging to controllably tune the secondary porous structure (pore in the outer shells) of the HPC support to improve the performance of the catalysts. Herein, a Ni-substituted ZIF-67 was used as a precursor to prepare HPC-supported catalysts. We found that Ni2+ can partially substitute Co2+ to create “defected structure” within ZIF-67, and the secondary pore structure of the derived HPC can be facilely tuned by adjusting the ratio of Ni2+ to Co2+. Catalyst HPC-Ni-ZIF–1 with hierarchical secondary pore and the largest pore volume exhibits an excellent catalytic performance for the hydrogenation of nitro compounds to corresponding amino compounds.

“…The combination of polycarboxylates with N-containing imidazole or pyridine derivatives is also a practical method for fabricating a variety of MOFs with intriguing architectures and topologies. Those MOFs not only exhibit a diverse range of attractive structures but also exhibit various functional features, including linker rotation, expansion/shrinkage and selective storage of guest molecules (Voda et al, 2017;Sun, Chen et al, 2019). To date, several groups have reported functional MOFs that combine dicarboxylate ligands with Ncontaining pyridine derivatives.…”

Four new coordination polymers, including 1D, 2D and 3D structures, were synthesized via a hydrothermal method using Cd2+/Zn2+/Cu2+ metal salts as nodes. These polymers were formed through self-assembly of four different dicarboxylic acid ligands, namely adamantane-1,3-dicarboxylic acid (H2adc), glutaric acid (H2glu), 5-hydroxyisophthalic acid (H2hip) and fumaric acid (H2fum), in conjunction with the auxiliary ligand [1,4-bis(pyridin-4-ylmethyl)piperazine (bpmp). The corresponding formulae are [Cd3(adc)2(bpmp)Cl2(H2O)2] n (1), {[Cd2(glu)2(bpmp)2(H2O)2]·8H2O·2CH3OH} n (2), [Zn(hip)(bpmp)(H2O)] n (3) and [Cu(fum)(bpmp)(H2O)2] n (4). Single-crystal X-ray diffraction studies revealed that the Cd2+ centers in complex 1 all adopt a six-coordinate mode but two distinct {CdO2N2Cl2} and {CuO5Cl} units. The 3D network of complex 1 can be simplified to a binodal (4.6)-connected underlying net with the point symbol (3·42·5·62)4(32·62·72·88·10). Each Cd2+ cation in complex 2 adopts a seven-coordinate {CdO5N2} center, forming an asymmetric pentagonal bipyramidal coordination. Its stacking structure is formed by the interaction of hydrogen bonds between 2D supramolecular layers, with the adjacent layers exhibiting mirror symmetry. Each Zn2+ ion in complex 3 displays a {ZnO3N} four-coordinate unit. Its stacking structure is formed by one-dimensional [Zn(hip)(bpmp)(H2O)] n chains connected through hydrogen bonds. On the other hand, complex 4 features a Jahn–Teller distorted {CuO4N2} octahedral coordination. Subsequently, the thermal stability of these complexes was investigated. The solid-state fluorescence spectroscopy was employed to analyze complexes 1, 2 and 3. Additionally, a Hirshfeld surface analysis was performed on complex 3.

“…In recent years, the design and synthesis of coordination polymers (CPs) have attracted much attention due to their fascinating molecular topologies and potential applications in catalysis, molecular detection, microelectronics, ion exchange, and nonlinear optics [4][5][6][7]. In general, the structural diversity of these crystal materials is decided by many factors such as counterions, templates, metal coordination ratio, metal ions, the value of pH, and the coordination of organic ligands [8][9][10]. In these specific strategies, the reasonable selection of the functional group, rigidity, and length of co-ligand or organic ligand is very significant for structure-controlled CPs assembly, and many important works have been completed via utilizing this strategy [11][12][13].…”

AbstractTwo novel mixed-ligand coordination polymers, {[Co(tdc)(btrp)]·0.67DMF}n (1) and {[Zn2(bimb)2(tdc)2]·2H2O}n (2) involving 2,5-thiophenedicarboxylate (H2tdc), and bitopic flexible N-donor ligands, 1,3-bis(1,2,4-triazol-1-yl)propane (btrp) and 1,4-bis((1H-benzo[d]imidazol-1-yl)methyl)benzene (bimb), have been synthesized by the hydrothermal method and characterized via IR, elemental analysis, thermal analysis, and powder X-ray diffraction. The biological functional studies were performed; the treatment activity of the compounds on periodontitis and the specific mechanism was explored. First, the real-time RT-PCR was carried out to determine the inflammatory genes nf-κb and p53 relative expression in periodontal mucosal cells after treating with compounds 1 and 2. Then, the level of the inflammatory cytokine in the gingival crevicular fluid after treating with compounds was also determined by the ELISA detection kit.
