The increasing dangerous chemical pollutants led by shipping accidents call for the new pollutant treatment strategy. In this work, a three-component hybrid {[(BiI6)I13]·2I3·(H-BPA)4}n (1) can be used in dye degradation seawater. highly interesting feature of 1 lies its unique 1-D Z-shape [(BiI6)I13]n6? infinite chain constructed from I···I contacts between mono-nuclear (BiI6)3? anions and I133...

The reaction of 1,4-diaminobutane with hydroiodic acid in the presence of iodine yields the title compound 1,4-diazaniumbutane tetraiodide, C4H14N2I4 (1). The title compound has been structurally characterized by crystallographic and spectroscopic methods (Raman and IR). 1 is built up by centrosymmetric 1,4-diazaniumbutane cations in all-trans conformation and linear I4 anions. Both, cations an...

Halogenated graphene derivatives are interesting owing to their outstanding physical and chemical properties. In this paper, we present various methods for the synthesis of iodinated graphene derivatives by the iodination of graphite oxides prepared according to either the Hummers or Hofmann method. Both graphite oxides were iodinated by iodine or hydroiodic acid under reflux or in an autoclave...

Partially oxidized linear chain transition metal complexes have found widespread interest recently, mainly because some such solids, with directly interacting metal ions in the chains, behave like one-dimensional metals [1-4]. The electrical conductivity of the linear hahde bridged species (mainly of the Wolffram's salt type) is, on the other hand, quite low [5-8]. Many of the linear-chain mixe...

Graphene nanoplatelets (GNPs), synthesized using potassium permanganate-based oxidation and exfoliation followed by reduction with hydroiodic acid (rGNP-HI), have intercalated manganese ions within the graphene sheets, and upon functionalization with iodine, show excellent potential as biomodal contrast agents for magnetic resonance imaging (MRI) and computed tomography (CT). Structural charact...

The complex of xylan and iodine and its formation in a solution of xylan, CaCl2, and I2+KI was investigated by UV/Vis, second-derivative UV/Vis, and Raman spectroscopy. The complex forms only at very high concentrations of CaCl2, suggesting that when the water available in the solution is not sufficient to fully hydrate the calcium cation the chelation with the hydroxyl groups of the xylan can ...
