Barium hydroxide is a chemical compound with the chemical formula Ba(OH)2. The monohydrate (x = 1), known as baryta or baryta-water, is one of the principal compounds of barium. This white granular monohydrate is the usual commercial form.
Selenic acid is the inorganic compound with the formula H2SeO4. It is an oxoacid of selenium, and its structure is more accurately described as O2Se(OH)2. It is a colorless compound. Although it has few uses, one of its salts, sodium selenate is used in the production of glass and animal feeds.
In chemistry tellurate is a compound containing an oxyanion of tellurium where tellurium has an oxidation number of +6. In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central tellurium atom.
Selenium trioxide is the inorganic compound with the formula SeO3. It is white, hygroscopic solid. It is also an oxidizing agent and a Lewis acid. It is of academic interest as a precursor to Se(VI) compounds.
Sodium selenate is the inorganic compound with the formula Na
2SeO
4, not to be confused with sodium selenite. It exists as the anhydrous salt, the heptahydrate, and the decahydrate. These are white, water-soluble solids. The decahydrate is a common ingredient in multivitamins and livestock feed as a source of selenium. The anhydrous salt is used in the production of some glass. Although the selenates are much more toxic, many physical properties of sodium selenate and sodium sulfate are similar.
Praseodymium(III) sulfate is a praseodymium compound with formula Pr2(SO4)3. It is an odourless whitish-green crystalline compound. The anhydrous substance readily absorbs water forming pentahydrate and octahydrate.
Barium permanganate is a chemical compound, with the formula Ba(MnO4)2. It forms violet to brown crystals that are sparingly soluble in water.
Zeitschrift für Kristallographie – New Crystal Structures is a bimonthly peer-reviewed scientific journal published in English. Its first issue was published in December 1997 and bore the subtitle "International journal for structural, physical, and chemical aspects of crystalline materials." Created as a spin-off of Zeitschrift für Kristallographie for reporting novel and refined crystal structures, it began at volume 212 in order to remain aligned with the numbering of the parent journal. Paul von Groth, Professor of Mineralogy at the University of Strasbourg, established Zeitschrift für Krystallographie und Mineralogie in 1877; after several name changes, the journal adopted its present name, Zeitschrift für Kristallographie – Crystalline Materials, in 2010.
Nickel is one of the metals that can form Tutton's salts. The singly charged ion can be any of the full range of potassium, rubidium, cesium, ammonium (), or thallium. As a mineral the ammonium nickel salt, (NH4)2Ni(SO4)2 · 6 H2O, can be called nickelboussingaultite. With sodium, the double sulfate is nickelblödite Na2Ni(SO4)2 · 4 H2O from the blödite family. Nickel can be substituted by other divalent metals of similar sized to make mixtures that crystallise in the same form.
A chloride nitride is a mixed anion compound containing both chloride (Cl−) and nitride ions (N3−). Another name is metallochloronitrides. They are a subclass of halide nitrides or pnictide halides.
A selenate selenite is a chemical compound or salt that contains selenite and selenate anions (SeO32- and SeO42-). These are mixed anion compounds. Some have third anions.
A tellurite tellurate is chemical compound or salt that contains tellurite and tellurate anions [TeO3]2- [TeO4 ]2-. These are mixed anion compounds, meaning the compounds are cations that contain one or more anions. Some have third anions. Environmentally, tellurite [TeO3]2- is the more abundant anion due to tellurate's [TeO4 ]2- low solubility limiting its concentration in biospheric waters. Another way to refer to the anions is tellurium's oxyanions, which happen to be relatively stable.
Germanium tetrabromide is the inorganic compound with the formula GeBr4. It is a colorless solid that melts near room temperature. It can be formed by treating solid germanium with bromine, or by treating a germanium-copper mixture with bromine:
Praseodymium orthoscandate is a chemical compound, a rare-earth oxide with a perovskite structure. It has the chemical formula of PrScO3.
Europium(III) arsenate is an arsenate salt of europium, with the chemical formula of EuAsO4. It has good thermal stability, with its pKsp,c of 22.53±0.03. It is a colorless crystal with a xenotime structure.
Barium selenide is an inorganic compound, with the chemical formula of BaSe. It is a white solid although typically samples are colored owing to the effects of air oxidation.
Strontium selenide is an inorganic compound with the chemical formula SrSe.
Nickel(II) selenate is a selenate of nickel with the chemical formula NiSeO4.
Lead(II) selenate is a selenate of lead, with the chemical formula PbSeO4.
Trimethylsulfoxonium (abbreviated TMSO) is a cation with a formula (CH3)3SO+ consisting of a sulfur atom attached to three methyl groups and one oxygen atom. It has a net charge of +1.
