Sodium cobaltinitrite is a salt of the coordination complex [Co(NO 2) 6] 3−. [1]In organometallic chemistry, transition metal complexes of nitrite describes families of coordination complexes containing one or more nitrite (−NO 2) ligands. [2]
A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO − 2) and nitrate (NO − 3) anions.They are mixed-anion compounds, and they are mixed-valence compounds.
Cisplatin, PtCl 2 (NH 3) 2, is a coordination complex of platinum(II) with two chloride and two ammonia ligands.It is one of the most successful anticancer drugs. A coordination complex is a chemical compound consisting of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands ...
Nitrite is an ambidentate ligand and can form a wide variety of coordination complexes by binding to metal ions in several ways. [2] Two examples are the red nitrito complex [Co(NH 3) 5 (ONO)] 2+ is metastable, isomerizing to the yellow nitro complex [Co(NH 3) 5 (NO 2)] 2+. Nitrite is processed by several enzymes, all of which utilize ...
Sodium hexanitritocobaltate(III) is an inorganic compound with the formula Na 3 [Co(NO 2) 6]. The anion of this yellow-coloured salt consists of the transition metal nitrite complex [Co(NO 2) 6] 3−. It was a reagent for the qualitative test for potassium and ammonium ions. [2]
The compounds Co(NO)(CO) 3 and Ni(CO) 4 illustrate the analogy between NO + and CO. In an electron-counting sense, two linear NO ligands are equivalent to three CO groups. This trend is illustrated by the isoelectronic pair Fe(CO) 2 (NO) 2 and [Ni(CO) 4]. [3] These complexes are isoelectronic and, incidentally, both obey the 18-electron rule.
In chemistry, linkage isomerism or ambidentate isomerism is a form of structural isomerism in which certain coordination compounds have the same composition but differ in which atom of the ligand is bonded to the metal. Typical ligands that give rise to linkage isomers are: cyanide, CN − – isocyanide, NC −; cyanate, OCN − – isocyanate ...
Being the conjugate base of a strong acid (nitric acid, pK a = -1.4), nitrate has modest Lewis basicity.Two coordination modes are common: unidentate and bidentate.Often, bidentate nitrate, denoted κ 2-NO 3, is bound unsymmetrically in the sense that one M-O distance is clearly bonding and the other is more weakly interacting.
