Ligands listed alphabetically

Acid Halogenides. For acid halogenides the name is formed from the corresponding acid radical if this has a special name (Sec. 3.1.2.10) for example, NOCl, nitrosyl chloride. In other cases these compounds are named as halogenide oxides with the ligands listed alphabetically for example, BiClO, bismuth chloride oxide VCI2O, vanadium(lV) dichloride oxide. 

Rule 4. Ligands listed alphabetically within classes. The ligands CO and CN are considered to be organic. 

Verify that the number of ligands matches the numerical prefixes in the name, that the ligands are listed alphabetically, and that the overall species is charge-neutral. 

When naming a complex, or when writing the formula for a complex, the ligands are listed alphabetically. Again, do not forget that metals are first in the formula and last in the name. 

Many other GPCRs mediate the effects of hormones and NTs involved in a wide variety of responses. Some of these are also targets for plant defensive compounds (Table 5.8) and are listed alphabetically for convenience in the outline presented below. Note that all of the hormones listed below are peptides except for (a) ATP, (c) anandamide, (j) melatonin and (p) some non-peptide sigma receptor ligands. 

Guidelines for the formulation of ligand abbreviations are given in Section IR-4.4.4 examples of such abbreviations are listed alphabetically in Table VII with diagrams of most shown in Table VIII. 

Ionic coordination compounds are named by first naming the cation and then the anion. Complex ions are named by listing the ligands in alphabetical order, followed by the metal and its oxidation state (as... 

List the names of the ligands in alphabetical Ammine (NH3) is listed before chloro (Cl ),... 

When you write the formula of a complex ion, write the symbol for the metal first, followed by neutral molecules and then anions. If there is more than one anion or neutral molecule acting as a ligand, list them in alphabetical order based on the chemical symbol. 

In empirical formulas of inorganic compounds, electropositive elements are listed first [3]. The stoichiometry of the element symbols is indicated at the lower right-hand side by index numbers. If necessary, the charges of ions are placed at the top right-hand side next to the element symbol (e.g., S "). In ions of complexes, the central atom is specified before the ligands are listed in alphabetical order, the complex ion is set in square brackets (e.g., Na2[Sn(OH)+]). 

Naming a Coordination Compound. To name a coordination compound, the names of the ligands are attached directly in front of the name of the central atom. The ligands are listed in alphabetical order regardless of the number of each and with the name of a ligand treated as a unit. Thus diammine is listed under a and dimethylamine under d. The oxidation number of the central atom is stated last by either the oxidation number or charge number. 

The Access Tables have been laid out in a manner that parallels the foregoing chapters. The first three tables provide listings according to element and ligand. Tables 4 to 18 and 20 correspond to the chapters of Volumes 1 and 5. Table 13 covers ligand synthesis. Two additional tables cover physical techniques for the study of complexes and thermochemistry. The final table is entitled Special Topics and includes aspects that defied inclusion under earlier headings and these aspects are listed purely in alphabetical order. 

The element symbols within each formula are arranged according to a modified Hill system in which the order is metal(s), C, H and then any remaining symbols arranged alphabetically. Compounds containing two (or more) different metals appear twice (or more), being listed under each metal. Common ligand abbreviations which appear in the text have also been used in the index. These include acac (acetylacetone), bipy (2,2 -bipyridyl), diars [o-phenylenebis(dimethyl-arsine)], dien (diethylenetriamine), etc. 

Sequence of central atom and ligand names. The ligands are listed in alphabetical order, without regard (o charge, before the names of the central atom. Numerical prefixes indicating the number of ligands are not considered in determining that order. 

In compositional nomenclature, ligands are given in alphabetical order before central atoms. Central atoms are listed in alphabetical order as well. Bridging ligands to the extent known are indicated by the p notation (see Section 3.2.3.4). The numbers of ligands and central atoms are indicated by the appropriate numerical prefixes (see Section 3.3.2). Anions, cations, oxidation states and ionic charges are indicated in the same manner as in mononuclear compounds (see Section 3.3.3). For examples see Table 14. 

Specific lUPAC nomenclature for organo-silicon compounds has not yet been developed. According to general lUPAC rules, the tetravalent compounds should be known as silanes and their ligands should be listed in alphabetical order and hydrogen should not be mentioned.
