sodium or potassium cyanide to a solution of nickel(II) ions in aqueous solution leads to the precipitation of nickel(II) cyanide tetrahydrate. On heating...

Iron(II) cyanide is an inorganic compound with the empirical formula Fe(CN)2. It may have a Fe2[Fe(CN)6] structure.[better source needed] Iron(II) cyanide...

employs nickel complexes as catalysts. RCH=CH2 + HCN → RCH2−CH2CN Four molecules of HCN will tetramerize into diaminomaleonitrile. Metal cyanides are typically...

Cyanide poisoning is poisoning that results from exposure to any of a number of forms of cyanide. Early symptoms include headache, dizziness, fast heart...

diamagnetic species, featuring low-spin iron(II) center in an octahedral ligand environment. Although many salts of cyanide are highly toxic, ferro- and ferricyanides...

NiAs nickel(II) arsenide 27016–75–7 Ni(BF4)2 nickel(II) fluoroborate 14708–14–6 NiBr2 nickel(II) bromide 13462–88–9 Ni(CN)2 nickel(II) cyanide 557–19–7...

substrate. Cyanide baths contain cuprous cyanide as the source of copper(I) ions, sodium or potassium cyanide as a source of free cyanide that complexes...

industrial reactor model. The crushed ore is irrigated with a dilute alkaline cyanide solution. The solution containing the dissolved precious metals in a pregnant...

state of +2. Nickel is classified as a transition metal with nickel(II) having much chemical behaviour in common with iron(II) and cobalt(II). Many salts...

sodium cyanide or cyanogen bromide in place of hydrogen cyanide. The reaction can be simplified by replacing the HCN/AlCl3 combination with zinc cyanide. Although...

group are not called nitriles, but cyanides instead. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly...

consisting of nickel atoms, and cyanide groups. The most important of these are the tetracyanonickelates containing four cyanide groups per nickel. The tetracyanonickelates...

suspected that the structure of palladium cyanide consists of square planar Pd(II) centers linked by cyanide bridging ligands, which are bonded through...

increasing rates. In the case of nickel-based systems, catalyst deactivation involves formation of dicyanonickel(II) species, which are unreactive toward...

developed: Nickel-catalyzed cyanations avoid the use of precious metals, and can take advantage of benzyl cyanide or acetonitrile as a cyanide source, via...

Cr(II), Mn(III), Mn(II), Fe(II), Fe(III), and Co(III) derivatives are low-spin, reflecting the strong binding of cyanide, i.e. cyanide ranks highly in the...

SS in and to free Elsa. Elsa poisons the Obersturmbannführer with his cyanide capsule, and a firefight between the remainder of the SS platoon and Heinrich...

compounds include a number of minerals and industrially important nickel compounds. Nickel(II) sulfate can crystallise with six water molecules yielding Retgersite...

solutions of nickel(II) salts with potassium cyanide. The synthesis is often conducted stepwise, beginning with precipitating solid nickel dicyanide coordination...

certain compounds of carbon with nitrogen and oxygen (e.g. cyanide ion CN−, hydrogen cyanide HCN, chloroformic acid ClCO2H, carbon dioxide CO2, and carbonate...
