Dipotassium zinc tetraiodate(V) dihydrate

چکیده
The title compound, K(2)Zn(IO(3))(4)·2H(2)O, contains two symmetry-independent K and I atoms. These atoms, as well as the Zn atom, are coordinated by shared O atoms and, moreover, the Zn atom is coordinated by two water mol-ecules in trans positions. The K, Zn and water O atoms atoms are situated in special positions on twofold symmetry axes. The hydrogen atoms are involved in strong O-H⋯O hydrogen bonds and O-H⋯I inter-actions also occur. The crystals of the title compound are, in general, twinned, but the sample used for this experiment was free of twinning.

The anion of the title compound, also called sygethin dihydrate, 2K(+)·C(18)H(20)O(6)S(2) (2-)·2H(2)O, has crystallographic inversion symmetry. The K(+) cation is surrounded by eight O atoms in a distorted cubic coordination geometry, forming extended K-O-S networks. There are also O-H⋯O hydrogen bonds.
متن کاملMorphological impact of zinc oxide layers on the device performance in thin-film transistors.
Zinc oxide thin-films are prepared either by spin coating of an ethanolic dispersion of nanoparticles (NP, diameter 5 nm) or by spray pyrolysis of a zinc acetate dihydrate precursor. High-resolution electron microscopy studies reveal a monolayer of particles for the low temperature spin coating approach and larger crystalline domains of more than 30 nm for the spray pyrolysis technique. Thin-fi...

The title compound, [Zn(C(10)H(11)N(4)O(2))(2)]·2H(2)O, was prepared by the reaction between Zn(CH(3)COO)(2)·2H(2)O and 2-hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propano-hydrazide (Hpop). The central Zn(II) atom has a distorted tetra-gonal-bipyramidal coordination geometry formed by two amide O atoms and four N atoms of two azomethine and two pyridine groups. In the crystal, complex mol-ecu...
متن کاملA rutile-type porous zinc(II)-phosphonocarboxylate framework: local proton transfer and size-selected catalysis.
The layered-solvothermal synthesis of zinc acetate dihydrate with 5-phosphonobenzene-1,3-dicarboxylic acid yields a three-dimensional rutile-type porous metal-organic framework, which is an anionic open-framework containing local proton transfer with hydrated protons and showing excellent size-selective properties.
متن کاملSynthesis and Characterization of Zinc Oxide Nanoparticles using Zinc Acetate Dihydrate and Sodium Hydroxide
Low-temperature aqueous chemical growth methods have shown great potential in the synthesis of ZnO nanostructures. Hexamethylenetetramine (HMTA) is the most common chemical substance used in the hydrothermal synthesis. In this study zinc oxide nanoparticles were prepared via hydrothermal growth using zinc acetate dihydrate and sodium hydroxide, as precursors instead of HMTA, as it is commercial...
