Gallium(II) sulfide, GaS, is a chemical compound of gallium and sulfur. The normal form of gallium(II) sulfide as made from the elements has a hexagonal layer structure containing Ga 2 4+ units which have a Ga-Ga distance of 248pm. [1] This layer structure is similar to GaTe, GaSe and InSe. [1] An unusual metastable form, with a distorted ...
Gallium also forms sulfides in lower oxidation states, such as gallium(II) sulfide and the green gallium(I) sulfide, the latter of which is produced from the former by heating to 1000 °C under a stream of nitrogen. [7]: 94 The other binary chalcogenides, Ga 2 Se 3 and Ga 2 Te 3, have the zincblende structure.
Ga 2 S 3 decomposes at high temperature forming the non-stoichiometric sulfide, Ga 4 S x (4.8 < x < 5.2). [5] Ga 2 S 3 dissolves in aqueous acids and decomposes slowly in moist air forming H 2 S. [2] Ga 2 S 3 dissolves in aqueous solutions of potassium sulfide, K 2 S to form K 8 Ga 4 S 10 containing the (Ga 4 S 10) 8− anion which has an ...
Gallium sulfide may refer to: Gallium(III) sulfide, Ga 2 S 3; Gallium(II) sulfide, GaS; Thiogallate cations containing gallium and sulfur This page was last edited on ...
Gallium(III) sulfide, Ga 2 S 3, has 3 possible crystal modifications. [37]: 104 It can be made by the reaction of gallium with hydrogen sulfide (H 2 S) at 950 °C. [33]: 162 Alternatively, Ga(OH) 3 can be used at 747 °C: [38] 2 Ga(OH) 3 + 3 H 2 S → Ga 2 S 3 + 6 H 2 O. Reacting a mixture of alkali metal carbonates and Ga 2 O 3 with H
Their proper names are gallium(III) fluoride, gallium(III) chloride, gallium(III) bromide and gallium(III) iodide. GaF 3 GaF 3 is a white solid which sublimes before it melts, with an estimated melting point above 1000 °C. [contradictory] It contains 6 co-ordinate gallium atoms with a three-dimensional network of GaF 6 octahedra sharing common ...
Sulfide (also sulphide in British English) [2] is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Gallium telluride can be made by reacting the elements or by metal organic vapour deposition . [1] GaTe produced from the elements has a monoclinic crystal structure. Each gallium atom is tetrahedrally coordinated by 3 tellurium and one gallium atom. The gallium-gallium bond length in the Ga 2 unit is 2.43 Angstrom.
