“…Each impc – ligand either connects three Cu II ions acting as a 3‐connected node or links to two Cu II ions acting as a 2‐connected node. The resulting 2D structure can be simplified as 3‐nodal (2,3,5)‐connected net with a Schläfli symbol of {(4.6 2 )(4 2 .6 5 .8 2 .10)(4)} as indicated by TOPOS software (Figure d), which hasn't been reported in previous literatures , …”

Five coordination compounds [Cu 2 (impc) 2 (μ 2-OH)Cl] n (1), [Cu 2 (impc) 2 (μ 2-OH)Br] n (2), [Co(impc) 2 (H 2 O) 2 ] n (3), [Co 4 (impc) 4 (SO 4) 2 (H 2 O)] n (4) and {[Co(impc)(H 2 O) 2 ]•H 2 O} (5) based on asymmetric 5-(1H-imidazole-1-yl)-3-pyridinecarboxylic acid (Himpc) have been hydrothermally synthesized and structurally characterized. 1 and 2 are isostructural and consist of binuclear Cu II units and display two-dimensional (2D) framework, where 1 and 2 present a new {(4.6 2)(4 2 .6 5 .8 2 .10)(4)} topology. 3 features a 1D chain structure. Polymer 4, which also displays a new Schläfli symbol {(4 13 .6 20 .8 8 .10 4)(4 3) 2 (4)}, contains tetranuclear Co II cluster and is a 2D structure. The planar-type tetranuclear Co II cluster with SO 4 2bridge in 4 has not been [a] Prof. J.

“…In addition, H 3 mtbd employs various coordination modes to interact with different metal caions owing to the triazole rotation. (ii) Similar ligands have been confirmed to be excellent connecting pieces for building metal complexes; , nevertheless, H 3 mtbd has seldom been adopted in the construction of CPs. In this article, the syntheses, crystal structures, and physical properties of two polymers, {[Er(Hmtbd)(H 2 mtbd)(H 2 O) 3 ]·2H 2 O} n ( 1 ) and [Yb(Hmtbd)(H 2 mtbd)(H 2 O) 3 ] n ( 2 ), were reported.…”

Two lanthanide coordination polymers (CPs) {[Er(Hmtbd)(H2mtbd)(H2O)3]·2H2O} n (1) and [Yb(Hmtbd)(H2mtbd)(H2O)3] n (2) carrying an N-heterocyclic carboxylate ligand 5-(3-methylformate-1H-1,2,4-triazole-1-methyl)benzen-1,3-dicarboxylate (H3mtbd) were prepared under solvothermal conditions. The single-crystal X-ray diffraction data demonstrate that 1 and 2 are isostructural and display 1D chain structure. Alternating current (AC) impedance measurements illustrate that the highest proton conductivities of 1 and 2 can attain 5.09 × 10–3 and 3.09 × 10–3 S·cm–1 at 100 °C and 98% relative humidity (RH), respectively. The value of 1 exceeds those of most reported lanthanide-based crystalline materials and ranks second among the described Er-CPs under similar conditions, whereas the value for 2 is the highest proton conductivity among the previous Yb-CPs. Coupled with the structural analyses of the two CPs and H2O vapor adsorption, the calculated E a values help to deduce their proton conductive mechanisms. Notably, the N-heterocyclic units (triazole), carboxyl, and hydrogen-bonding network all play key roles in the proton-transfer process. The prominent proton conductive abilities of both CPs show great promise as efficient proton conductors.

“…Furthermore, there has been recent interest in the terpyridine moiety, not only because of its exciting molecular topologies in the design and synthesis of polymers for coordination but also because they have strong anti-microbial activity, which could provide an important point of reference for more effective anti-microbial drug design [41][42][43][44][45][46][47][48]. This increased lipophilicity can lead to a breakdown of the cell permeability barrier, thereby blocking normal cell processes [49][50][51][52]. Previous studies [53,54] showed that bidentate or tridentate ligands with greater lipophilicity had higher anti-microbial activity than monodentate ligands and, as stated by the principle of similarity and inter-miscibility, two different types of ligands in complexes had stronger anti-bacterial activity than a single ligand.…”

A series of different substituted terpyridine (tpy)-based ligands have been synthesized by Kröhnke method. Their binding behaviour was evaluated by complexing them with Co(II), Fe(II) and Zn(II) ions, which resulted in interesting coordination compounds with formulae, [Zn(tpy) 2 ]PF 6 , [Co(tpy) 2 ](PF 6 ) 2 , [Fe(tpy) 2 ](PF 6 ) 2 and interesting spectroscopic properties. Their absorption and emission behaviours in dilute solutions were investigated in order to explain structure–property associations and demonstrate the impact of different aryl substituents on the terpyridine scaffold as well as the role of the metal on the complexes. Photo-luminescence analysis of the complexes in acetonitrile solution revealed a transition from hypsochromic to bathochromic shift. All the compounds displayed remarkable photo-luminescent properties and various maximum emission peaks owing to the different nature of the functional groups. Furthermore, the anti-microbial potential of ligands and complexes was evaluated with docking analyses carried out to investigate the binding affinity of terpyridine-based ligands along with corresponding proteins (shikimate dehydrogenase and penicillin-binding protein) binding sites. To obtain further insight into molecular orbital distributions and spectroscopic properties, density functional theory calculations were performed for representative complexes. The photophysical activity and interactions between chromophore structure and properties were both investigated experimentally as well as theoretically.
