Abstract. The interdigitated coordination networks [Cu(tyty)] (1) and [Cu 1.5 (L1)(L2)(tyty)] (2) [Htyty = 5-(4-(1H-1,2,4-triazol-1-yl)phenyl)-1H-tetrazole, HL1 = 2,3,4,5-tetrachlorobenzoic acid, HL2 = 2,3,4,5,6-pentachlorobenzoic acid], were hydrothermally synthesized and further characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, IR and UV/Vis spectroscopy, and TG analyses. Compound 1 consists of unique 2D double-bilayers, which

Construction and properties of cobalt(ii)/copper(ii) coordination polymers based on N-donor ligands and polycarboxylates mixed ligands

5Metal-organic coordination polymers (MOCPs) are well known organic-inorganic hybrids with infinite structures consisting of metal ions/clusters and organic ligands linked through coordination interactions. MOCPs can be constructed from one or more than one organic bridging ligands (mixed-ligands) and different metal ions. The previous reports prove the fact that the nature of organic ligands and metal ions dominates the final structures as well as properties of the MOCPs in a certain way. Therefore, we focus 10 on discussing the cobalt(II)/copper(II) coordination polymers constructed from the mixed-ligands of polycarboxylates and N-donor ligands, which may possess potential applications in the fields of electrochemistry, electrocatalysis, magnetism and photocatalysis. In this review, we summarize some typical Co(II)/Cu(II) MOCPs based on the mixed bridging organic ligands, aimed to discuss their versatile synthesis methods, topologies and structural influence factors, as well as their tunable properties. 15 All of these aspects are highlighted in this review, which seeks to guide further investigations of cobalt(II)/copper(II) coordination polymers. 65 shown that bis(imidazole)/bis(triazole)/bis(pyridyl) derivatives and polycarboxylate ligands represent the most reliable and typical building blocks which can be jointly applied to synthesize a wide range of desired coordination networks. 13-16 A choice of such connectors in coordination assembly can be rationalized 70 based on the following considerations: (i) the neutral N-donor ligands normally bind to the cobalt(II)/copper(II) ions as the rodlike bidentate tectons; (ii) the polycarboxylate ligands can not

“…Meanwhile, some MOFs have been found to be effective for light harvesting and behave as semiconductors, which provide the possibility to use MOFs as photocatalysts (Horiuchi et al 2012(Horiuchi et al , 2013Nasalevich et al 2014;Sha et al 2014;Wang et al 2012;Zhang and Lin 2014). Photocatalytic degradation of organic compounds, especially organic dyes over MOFs, has thus been investigated since a few years ago (Das et al 2011;Du et al 2011;Guo et al 2012;Laurier et al 2013;Liu et al 2013;Mahata et al 2006;Yang et al 2012). Moreover, some studies have already shown that it is available as a semiconductor carrier.…”

A CdS embedded metal-organic framework (MIL-100) composite was synthesized and used for photocatalytic degradation of nitrite ions. The obtained samples were characterized by a series of techniques such as X-ray diffraction (XRD), N 2 adsorption/desorption, transmission electron microscopy (TEM) and UVVis diffuse reflectance spectra (DRS). The results show that CdS nanoparticles were dispread and embedded on the MIL-100 crystals. The CdS/MIL-100 composites exhibited significant activities for photocatalytic degradation of nitrite ions through a disproportionation process in a neutral aqueous solution without any sacrificial reagents. When 20 wt% of CdS was embedded, the highest degradation yield of 92 % was achieved in 10-ppm NaNO 2 aqueous solution under simulated solar light irradiation, which was fivefold of bare CdS. The enhancement in photocatalytic activities could be contributed to photosensitization and supporting of metalorganic framework scaffold.
