Cations naming simple

The name of a coordination compound (as distinct from a complex cation or anion) is built in the same way as that of a simple compound, with the cation named before the anion ... 

If the compound is a salt, name the cation first and then the anion, just as in naming simple salts (Section 2.10). For example, K3[Fe(CN)6] is potassium hexacyanof errate(III). 

Naming polyatomic ions is not as easy as naming simple cations and anions. Even so, there are rules you can follow to help you remember how to name some of them. 

Another way of examining the mechanism of proton transfer is by comparing its temperature dependence with that of other monoatomic cations. Plots of the molar conductance of three cations, namely, H, Li, and K, on a logarithmic scale are shown as a function of reciprocal temperature in the range 5-55°C in fig. 6.14. Excellent linear plots are found from which an energy barrier associated with the process may be calculated. Using a simple Arrhenius expression, the temperature dependence of X,- for a small temperature interval is given by... 

The specific combination of ions in a coordination compound is the key to writing its formula and name. A coordination compound can consist of a complex cation with simple anionic counter ions, a complex anion with simple cationic counter ions, or even a complex cation with complex anion as counter ion.

This is a term introduced by Gokel and co-workers only very recently. The compounds included in this class are those which have single macrorings like crowns but additional pendant donor groups which make them similar in some respects to crytands. The presumption from which the name derives is that a complexed cation will be bound by both the macroring and the sidechain in much the same fashion as a lasso binds an animal. The compounds are named as simple crown derivatives and are illustrated as 16 a 17 below. 

Coordination compounds are named in much the same way as simple ionic compounds. The cation is named first, followed by the anion. Examples include... 

There are two ways to further reduce the X Me ratio to a value lower than 3. The first is to arrange simple similar to coordination type structure that requests steric similarity of all cations so as to be able to occupy octahedral voids. This method will be discussed separately. The second way is to arrange the linking of the octahedrons so as to render additional structural elements, namely pentagonal "blocks". 

The origin of cyclopropenone chemistry goes back to the successful preparation of stable derivatives of the cyclopropenium cation <5 3), the first member of a series of Huckel-aromatic monocyclic carbo-cations possessing a delocalized system of (4n + 2)-7r-electrons. This experimental confirmation of LCAO-MO theory stimulated efforts to prepare other species formally related to cyclopropenium cation by a simple resonance description of electron distribution, namely cyclopropenone 7 and methylene cyclopropene (triafulvene) 8 ... 

In general, most alkali borates are soluble, whereas most other borates are insoluble. Table 7.1 presents the names, formulas, states, solubilities, and standard free energies of a number of the more important simple inorganic species of B. All borate salts are white unless they contain a colored cation. 

Nciming a simple ionic compound is easy. You pair the name of the cation with the neune of the anion and then change the ending of the anion s ncime to -ide. The cation always precedes the anion in the final name. For example, the chemical name of NaCl (a compound made up of one sodium atom and one chlorine atom) is sodium chloride. 

Alternative names for cations obtained formally by the addition ofhydrons to mono nuclear binary hydrides. Names for these simple cations can be derived as described above. Alternatively, they may be named by adding the ending -onium to a stem of the element name.
