Poly[[diaquatetrakis(μ2-benzene-1,4-dicarbonitrile-κ2 N:N′)iron(II)] bis[tetrachloridoferrate(III)] nitromethane tetrasolvate]
In the title compound, {[FeII(C8H4N2)2(H2O)2][FeIIICl4]2·4CH3NO2}n, the FeII and FeIII ions are hexa- and tetracoordinated, respectively. Each unique benzene-1,4-dicarbonitrile molecule lies across a crystallographic inversion centre and bridges two FeII ions (each situated on an inversion centre), generating two-dimensional (4,4) square grid layers. The tetrachloridoferrate(III) anions and nitromethane solvent molecules lie between the square grid layers and are further link to the adjacent layers into a three-dimensional supramolecular structure through O—H⋯Cl and O—H⋯O hydrogen bonds
Synthesis of Encapsulated Zn(8-hydroxyquinoline) 2
The Zn(8-hydroxyquinoline)2(H2O)2, ZnQ2·2H2O, encapsulated in the porous BioMOF1 (ZnQ2@BioMOF1) host was synthesized by solid-solid and solid-solution reaction between Zn2+@BioMOF1 and 8-hydroxyquinoline. To prepare Zn2+@BioMOF1, dimethylammonium (DMA+), guests in the pores of BioMOF1 were replaced by Zn2+ ions via ion exchange process. The synthesized compound was characterized by XRD and TGA to confirm stability of BioMOF1 host. The ZnQ2·2H2O forming by metal-cation-directed de novo coassembly approach was confirmed by UV, IR, Fluorescence, BET, and confocal microscopy. Scanning electron microscopy images show slight change in morphology of BioMOF1 after introducing ZnQ2·2H2O by solid-solution reaction into its pores. Thin films of the produced materials were used to sense dissolved oxygen in water by using fluorescence technique
In situ Generated Copper(II)‐Quinoline Complexes as Robust and Versatile Photocatalysts for the Chlorosulfonylation of Olefins
A series of copper complexes was synthesized and studied as photocatalysts for the chlorosulfonylation of olefins. Featuring a tetradentate ligand consisting of one amino quinoline and two methyl pyridine moieties, the resulting Cu(II)-complex is effective under visible light irradiation to add sulfonyl chlorides to alkenes and alkynes, including unactivated aliphatic olefins. A weak base additive such as Na2CO3 prevents catalyst poisoning, resulting in an improvement of reaction yields and catalyst lifetime. A broad scope of sulfonyl chlorides and alkenes/alkynes as coupling partners are amenable for the title process, including examples previously reported unsuccessful with established copper-based photocatalysts

Crystal structure of poly[(2,2′-bipyridine-κ2N,N′)tetra-μ2-cyanido-κ4C:N;κ4N:C-manganese(II)disilver(I)]
The title compound, [Ag2Mn(CN)4(C10H8N2)]n or Mn(bipy){Ag(CN)2}2 (bipy = 2,2′-bipyridine) is isostructural with Cd(bipy){Au(CN)2}2 [Guo et al. (2009). CrystEngComm, 11, 61–66]. The MnII atom has crystallographically imposed twofold symmetry and a distorted octahedral coordination sphere consisting of six N atoms from one bipyridine ligand and four dicyanoargentate(I) anions, [Ag(CN)2]−, while the AgI atom of the complex anion displays the expected linear geometry. Each [Ag(CN)2]− unit connects to two neighbouring [Mn(bipy)]2+ cations to give an threefold interpenetrating quartz-like three-dimensional framework. No directional interactions beyond van der Waals contacts are observed
