Cuprous Nitrate
Copper(I) nitrate is a proposed inorganic compound with formula of CuNO3. It has not been characterized by X-ray crystallography. It is the focus of one publication, which describes unsuccessful efforts to isolate the compound. Another nonexistent simple copper(I) compound derived from an oxyanion is cuprous perchlorate. On the other hand, cuprous sulfate is known. Derivatives The nitrate salt of the acetonitrile complex, i.e., u(MeCN)4O3, is generated by the reaction of silver nitrate with a suspension of copper metal in acetonitrile. :Cu + AgNO3 + 4 CH3CN → u(CH3CN)4/sub>NO3 + Ag Tertiary phosphine complexes of the type u(P(C6H5)3)3O3 are prepared by the reduction of copper(II) nitrate Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu( NO3)2(H2O)x. The hydrates are blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C. Common hy ... by the phosphine. Referenc ...

Inorganic Compound
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemistry''. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep mantle remain active areas of investigation. Some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon (graphite, diamond, buckminsterfullerene, etc.), carbon monoxide, carbon dioxide, carbides, and the following salts of inorganic anions: carbonates, cyanides, cyanates, and thiocyanates. Many of these are normal parts of mostly organic systems, including organisms; describing a chemical as inorganic does not necessarily mean that it does not occur within living things. History Friedrich Wöhler's conversion of ammonium cyanate into urea in 1828 is often cited as the starting point of modern ...

X-ray Crystallography
X-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their crystallographic disorder, and various other information. Since many materials can form crystals—such as salts, metals, minerals, semiconductors, as well as various inorganic, organic, and biological molecules—X-ray crystallography has been fundamental in the development of many scientific fields. In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various mat ...

Cuprous Sulfate
Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu2 SO4. It is a white solid that has attracted little attention, in contrast to copper(II) sulfate. It is an unusual example of a copper(I) compound derived from an oxyanion, illustrated also by the non- or fleeting existence of cuprous nitrate and cuprous perchlorate. Structure Cu2SO4 crystallizes in the orthorhombic space group Fddd. Each oxygen in a sulfate anion is bridged to another sulfate by a copper atom, and the Cu-O distances are 196 pm. Synthesis Cuprous sulfate is produced by the reaction of copper metal with sulfuric acid at 200 °C: 2Cu + 2 H2SO4 -> Cu2SO4 + SO2 + 2 H2O Cu2SO4 can also be synthesized by the action of dimethyl sulfate on cuprous oxide: Cu2O + (CH3O)2SO2 -> Cu2SO4 + (CH3)2O The material is stable in dry air at room temperature but decomposes rapidly in presence of moisture or upon heating. It decomposes into copper(II) sulfate pentah ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Acetonitrile Complex
Transition metal nitrile complexes are coordination compounds containing nitrile ligands. Because nitriles are weakly basic, the nitrile ligands in these complexes are often labile. Scope of nitriles Typical nitrile ligands are acetonitrile, propionitrile, and benzonitrile. The structures of u(NH3)5(NCPh)sup>n+ have been determined for the 2+ and 3+ oxidation states. Upon oxidation the Ru-NH3 distances contract and the Ru-NCPh distances elongate, consistent with amines serving as pure-sigma donor ligands and nitriles functioning as pi-acceptors. Synthesis and reactions Acetonitrile, propionitrile and benzonitrile are also popular solvents. Because nitrile solvents have high dielectric constants, cationic complexes containing a nitrile ligand are often soluble in a solution of that nitrile. Some complexes can be prepared by dissolving an anhydrous metal salt in the nitrile. In other cases, a suspension of the metal is oxidized with a solution of NOBF4 in the nitrile: :Ni + 6 Me ...

Copper(II) Nitrate
Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu( NO3)2(H2O)x. The hydrates are blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C. Common hydrates are the hemipentahydrate and trihydrate. Synthesis and reactions Hydrated copper(II) nitrate Hydrated copper nitrate is prepared by treating copper metal or its oxide with nitric acid: :Cu + 4HNO3 → Cu(NO3)2. + 2H2O + 2NO2 The same salts can be prepared treating copper metal with an aqueous solution of silver nitrate. That reaction illustrates the ability of copper metal to reduce silver ions. In aqueous solution, the hydrates exist as the aqua complex u(H2O)6sup>2+. Such complexes are highly labile owing to the d9 electronic configuration of copper(II). Attempted dehydration of any of the hydrated copper(II) nitrates by heating affords the oxides, not Cu(NO3)2. At 80 °C, the hydrates convert to "basic copper nitrate ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
