Organocerium chemistry is the science of organometallic compounds that contain one or more chemical bond between carbon and cerium. These compounds comprise a subset of the organolanthanides. Most organocerium compounds feature Ce(III) but some Ce(IV) derivatives are known.
Uranium triiodide is an inorganic compound with the chemical formula UI3. It is a black solid that is soluble in water.
Chromium(II) selenide is an inorganic compound with the chemical formula CrSe. It crystalizes in a hexagonal structure with space group P63/mmc. It is one of many related Chromium-Selenium phases, including Cr7Se8, Cr3Se4, Cr0.68Se, Cr2Se3, and Cr5Se8. The compound has been described as an antiferromagnet, but its inverse magnetic susceptibility does not match the behavior expected for an antiferromagnet according to the Curie–Weiss law. One suggestion was that the Néel temperature is at 320 K, as the temperature where the compound has maximum specific heat. When synthesized as single atomic layer, CrSe is ferromagnetic, with a Curie Temperature of around 280 K.
Vinyllithium is an organolithium compound with the formula LiC2H3. A colorless or white solid, it is encountered mainly as a solution in tetrahydrofuran (THF). It is a reagent in synthesis of organic compounds, especially for vinylations.
Magnesocene, also known as bis(cyclopentadienyl)magnesium(II) and sometimes abbreviated as MgCp2, is an organometallic compound with the formula Mg(η5-C5H5)2. It is an example of an s-block main group sandwich compound, structurally related to the d-block element metallocenes, and consists of a central magnesium atom sandwiched between two cyclopentadienyl rings.
Magnesium anthracene is an organomagnesium compound that is almost invariably isolated as its adduct with three tetrahydrofuran (thf) ligands. With the formula Mg(C14H10)(thf)3, this air- and water-sensitive orange solid is obtained by heating a suspension of magnesium in a thf solution of anthracene.
SYM-2081 is a highly selective agonist for the kainate receptor. This potent agonist has nearly 3,000 fold- and 200-fold selectivity for kainate receptors over AMPA and NMDA receptors, respectively. Given its potency and selectivity, it is a useful ligand for studying the role of kainate receptors in the central nervous system.
Neodymium(II) iodide or neodymium diiodide is an inorganic salt of iodine and neodymium the formula NdI2. Neodymium uses the +2 oxidation state in the compound.
In chemistry, a transition metal ether complex is a coordination complex consisting of a transition metal bonded to one or more ether ligand. The inventory of complexes is extensive. Common ether ligands are diethyl ether and tetrahydrofuran. Common chelating ether ligands include the glymes, dimethoxyethane (dme) and diglyme, and the crown ethers. Being lipophilic, metal-ether complexes often exhibit solubility in organic solvents, a property of interest in synthetic chemistry. In contrast, the di-ether 1,4-dioxane is generally a bridging ligand.
Manganese(III) chloride is the hypothetical inorganic compound with the formula MnCl3.
Indium(I) chloride is the chemical compound with the formula InCl. Indium monochloride occurs as a yellow cubic form below 120 °C and above this temperature as a red orthorhombic form. InCl is one of three known indium chlorides.
Trimesitylvanadium (mesityl or Mes = 2,4,6-trimethylphenyl) is one of the organovanadium complexes with an oxidation state of vanadium of 3. This compound was first synthesized by W. Seidel and G. Kreisel in 1974. To prepare this compound, VCl3(THF)3 (THF = tetrahydrofuran) was reacted with Grignard reagent MesMgBr to form a blue solution at room temperature. It is precipitated by the addition of dioxane, which results in a blue solid. It is thermally stable, but it is also an air-sensitive compound.
