Two semiconducting hybrid gallium selenides, [Ga6Se9(C6H14N2)4][H2O] (1) and [C6H14N2][Ga4Se6(C6H14N2)2] (2), were prepared using a solvothermal method in the presence of 1,2-diaminocyclohexane (1,2-DACH). Both materials consist of neutral inorganic layers, in which 1,2-DACH is covalently bonded to gallium. In 1, the organic amine acts as a monodentate and a bidentate ligand, while in 2, bident...

A promising strategy for the controlled synthesis of inorganic/polymeric nanocomposites may be sustained by fabricating cross-linked PbS nanoparticles/polymer composite thin films through combining surface-initiated atom transfer radical polymerization (ATRP) and gas/solid reaction. The introduction of Pb ions through the extension of surface-initiated ATRP to the monomers containing metal ions...

A hydrogen-bonded chloride-hydrate assembly {[(H2O)4Cl2]2−}∞ has been ion-countered by the complex cations [Fe([9]aneS3)2] ([9]aneS3 = 1,4,7-trithiacyclononane). In {[(H2O)4Cl2]2−}∞, four water molecules and two chloride ions are self-assembled to form a one-dimensional supramolecular array of O–H· · ·O and O–H· · ·Cl hydrogen bonding, which consists of fused fourand six-membered rings. The dis...

When incorporated in membranes, Ag0 nanoparticles are effective antifouling and antibacterial agents, arising from the presence of Ag+ ions either in solution or adsorbed onto nanoparticles. A vari...

A porous coordination polymer, {[Eu(dpdo)4(H2O)3]H(SiMo12O40)(dpdo)0.5(CH3CN)0.5(H2O)4}n (1), (where dpdo is 4,4′-bipyridine-N,N′-dioxide) templated by double-Keggin-type polyanions has been synthesized through the self-assembly of Eu(III) ions and dpdo in acetonitrile/water solution and structurally characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. The X-ray...

The crystal structure of the title compound, {[Ba(C4HO4)2(H2O)5]·H2O} n , consists of discrete double chains propagating along [010]. The chains are formed by Ba(II) ions linked by bridging hydrogen squarate ligands in a trans-bis-monodentate mode. In addition, the bridging hydrogen squarate ligands connect the chains into a ladder structure via a third coordinating O atom. The remaining coordi...

In this study a new method by Application of graphene oxide Nano sheets– Melamine –TioOxalic acid composite was exhibited as adsorbent for the elimination of toxic mercury (II) ions from aqueous solutions. The combine has the authority to adsorb the organic and inorganic combines. Through the immobilization of Melamine-TioOxalic acid (MTO) onto graphene oxide nanosheets, the desired composite w...

State-of-the-art chemical bonding analyses show that water clusters have a bifunctional catalytic role in the formation of H2SO4 in acid rain. The embedded H2O monomers mitigate the change in the chemical bonding scenario of the rate-limiting step, reducing thereby the corresponding activation energy in accordance with Hammond's postulate. We expect that the insights given herein will prove use...
