“…First attempts to obtain crystals of complex 1 large enough to be delaminated were done following a methodology slightly different to that previously described [26] . In a typical experiment, an aqueous solution of 2,5pydc and triethylamine was mixed with an aqueous solution of Cu(CH 3 COO) 2 ·4H 2 O at room temperature for one day.…”

“…Herein we do demonstrate how such information can be put into practice to obtain stable colloidal dispersions of NSs in water with enhanced catalytic properties. As a proof-of-concept, we have selected the previously reported complex [Cu(2,5pydc)(H 2 O)] n ·2H 2 O ( 1 ), where 2,5pydc stands for 2,5-pyridine dicarboxylic acid [26] . The structure is made of Cu(II) ions coordinated to the carboxylic and pyridine groups of the 2,5pydc ligand forming 2D layers while water solvent molecules help to stabilize the 3D packing through hydrogen bonds.…”

Complexes of copper (II) nicotinate with acid amides were synthesized to vary the composition and the individual properties of the compounds obtained through coordination of the nicotinate group to acetamide, carbamide, thiocarbamide and nicotinamide (L1, L2). The coordination of the organic ligands, the environment of the central ion and the thermal behaviour of the synthesized compounds were elucidated by vibrational spectroscopy and thermal analysis. The relative intensities and the spatial structures of copper (II) nicotinate and the synthesized complexes showed that the new coordination compounds differ from each other and the original components, as they have unique crystal lattices. X-ray diffraction (XRD) analysis was used to obtain diffraction patterns of free molecules of ligands, copper nicotinate, and synthesized coordination compounds. The thermal behaviour of the synthesized compounds was investigated and the thermolysis products were identified. The stepwise decomposition of the synthesized compounds was found with several endo - and exo effects correspond to the decomposition of the constituent parts of the complexes. Based on the intensity of the electronic spectrum of diffuse reflection and the values of the bands, the six-coordination environment of Cu (II) the synthesized complexes was proven.

“…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.
