Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu(NO 3) 2 (H 2 O) x. The hydrates are hygroscopic blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C. [5] [6] Common hydrates are the hemipentahydrate and trihydrate.
Thus copper(II) nitrate readily dissociates in aqueous solution to give the aqua complex: Cu(NO 3) 2 + 6 H 2 O → [Cu(H 2 O) 6](NO 3) 2. Pyrolysis of metal nitrates yields oxides. [18] Ni(NO 3) 2 → NiO + NO 2 + 0.5 O 2. This reaction is used to impregnate oxide supports with nickel oxides. Nitrate reductase enzymes convert nitrate to
Crystals of hydrated copper(II) sulfate consist of [Cu(H 2 O) 4] 2+ centers linked to SO 2− 4 ions. Copper is surrounded by six oxygen atoms, provided by two different sulfate groups and four molecules of water. A fifth water resides elsewhere in the framework but does not bind directly to copper. [6]
Copper(I) forms only labile complexes with ammonia, including the trigonal planar [Cu(NH 3) 3] +. [14] Silver gives the diammine complex [Ag(NH 3) 2] + with linear coordination geometry. [15] It is this complex that forms when otherwise rather insoluble silver chloride dissolves in aqueous ammonia. The same complex is the active ingredient in ...
Hydrotalcite can contain carbonate and nitrate ions between its layers. Magnesium can be substituted by nickel, cobalt or copper. [1] Oxycarbonitrates containing an alkaline earth metal and cuprate and nitrate and carbonate anions in layers, form a family of superconducting materials. [2]

The nitrate salt of the acetonitrile complex, i.e., [Cu(MeCN) 4]NO 3, is generated by the reaction of silver nitrate with a suspension of copper metal in acetonitrile. [2] Cu + AgNO 3 + 4 CH 3 CN → [Cu(CH 3 CN) 4]NO 3 + Ag. Tertiary phosphine complexes of the type [Cu(P(C 6 H 5) 3) 3]NO 3 are prepared by the reduction of copper(II) nitrate by ...
