The title compound, hexa-mu-chloro-1:2kappa(4)Cl;2:3kappa(4)Cl;3:4kappa(4) Cl-hexachlor o-1kappa(2)Cl,2kappaCl,3kappaCl, 4kappa(2)Cl-hexakis(diethylamine)-1kappa(2)N,2kappa N,3kappaN, 4kappa(2)N-tetraindium(III), [(InCl(3))(4)(Et(2)NH)(6)] or [In(4)Cl(12)(C(4)H(11)N)(6)], lies about an inversion centre and consists of four octahedrally coordinated In centres linked by bridging Cl atoms to form ...
The structure of scandium indium penta-deca-molybdenum nona-deca-selenide, Sc1.91In1.39Mo15Se19, is isotypic with In2.9Mo15Se19 [Grüttner et al. (1979 ▸). Acta Cryst. B35, 285-292]. It is characterized by two cluster units Mo6Se (i) 8Se (a) 6 and Mo9Se (i) 11Se (a) 6 (where i represents inner and a apical atoms) that are present in a 1:1 ratio. The cluster units are centered at Wyckoff position...
Light emitting diodes (LEDs) are widely used nowadays. They are used in major parts of our life. But it is still necessary to improve their characteristics. In this paper the impurity and Indium atoms influence on the LEDs characteristics is investigated by computer simulation. Simulation was carried out in Sim Windows. The program was improved for this purpose by creating new files for AlGaInN...
Molecular mechanisms and precursor conversion pathways associated with the reactions that generate colloidal nanocrystals are crucial for the development of rational synthetic protocols. In this study, Fourier transform infrared spectroscopy technique was employed to explore the molecular mechanism associated with the formation of tin-doped indium oxide (ITO) nanocrystals. We found that the rea...
In this paper high resolution transmission electron microscopy analysis is performed on indium gallium zinc oxide thin film transistors to determine the crystal structure of the material. The relative elemental concentrations of indium, gallium, zinc and oxygen were quantified and analyzed using energy dispersive spectroscopy before and after subjection to positive gate bias temperature stress ...
We report an indium triflate-catalyzed stereoselective intramolecular tandem conjugate addition of secondary amines to α,β-bisenones to afford a 1,2,3-trisubstituted six-membered ring bearing diketone substituents in good to excellent yields at room temperature. Various kinds of α,β-bisenones and amines were employed to expand the scope of this chemistry. Intramolecular trapping of indium-enola...
A convergent one-step transformation of tetrahydropyranyl (THP) ethers is described. According to our earlier experiments, indium(III) triflate has proven to be an efficient catalyst for the transformation of THP ethers into their corresponding acetates. In further intensive work, we have developed a useful transforming reaction of THP ethers using various anhydride moieties. Indium(III) trifla...
Indium trichloride reacts with 2 moles of monothiodibenzoylmethane (LH ) in the presence of sodium acetate to yield InC l2L(LH ). According to an X-ray structure analysis the molecule possesses a hexacoordinated indium atom with two chlorine atoms in cis position and two sulfur atoms in trans position. The symmetry of the molecule is C2 imposed by a crystallographic twofold axis. The unique hyd...
