Composite anion

Metal complexes of chiral bis(oxazoline) ligands, in most cases Cu(II) complexes, have been supported by cationic exchange on inorganic, organic, and composite anionic solids. [Pg.173]

The resolution of the above-mentioned conflicts is not yet clear, but this author thinks that a profitable approach can be made by investigating the nature of the different complexes that may be involved. This line of thought was catalysed partly by the papers from the Jena school concerning the formation of a variety of complexes between cations and molecules [8, 9]. Unfortunately, this extensive work is less valuable than it might be and difficult to use because no account was taken of the intervention of binary ionogenic equilibria (BIE) in the systems studied. These mostly comprise trityl and tropylium ions and a variety of composite anions of the MtX n+1, type, i.e., typical components of BIE [10]. [Pg.330]

Composite anions have been constructed from assemblies of relatively simple, usually lacunary, polytungstate anions. Examples inclnde [Ln2(H20)2 SbW9033 (W50i8)2] (molar mass 5056 Ln = Y, Sm, Er), [Ce4(0H)2(H20)9 P2Wi6 059 2] " (molar mass 8652), [Ln(Ln2(0H)(H20)n(W04)4 AsW9033 4] ° (molar mass 10 529 Ln = Ce, Nd,...

Recent years have seen the reports of increasing numbers of very large polyoxometalate anions. These may be divided into two classes (i) composite anions constructed of assemblies of simpler, usually lacunary, polyanions and (ii) mixed-valence polymolybdate anions which comprise common building blocks, e.g., Mo8, Mo6, and Mo2 clusters that have no separate, stable existence.

A few common composite anions have names ending in -ide, namely, -OH hydroxide -CK cyanide -NH2 amide -NH- imide - NH KH2 hydrazide -NH OH hydroxylamide. Treating these as the other -ide names we obtain HaOH sodium hydroxide, KGN potassium cyanide, and the like. Sodium amide (NaNH2) is often abbreviated to sodamide, but there is no need for this practice. Hydrogen azide seems... [Pg.14]
