Alphabetical order ligands

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. 

Negatively coordinated groups are given before neutral coordinated groups in the examples of Werner scheme names above. Ewens and Bassett presented good reasons why that order should be reversed. The lUPAC rules (20) recommend that ligands be cited in alphabetical order regardless of their... 

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. 

Ligands are named in alphabetical order, ignoring the Greek prefix that indicates the number of each one present. 

Within the complex, first name the ligands in alphabetical order, and then name the metal. 

In naming a complex ion, the ligands are named in alphabetical order. A prefix that is used to indicate the number of ligands is not considered as part of the name of the ligand. For example,... 

Multiple bridging ligands between the pair of central atoms are cited in alphabetical order. Italicised element symbols indicating the coordinating atoms in bridging ligands are cited in the order of direction of the CRU and are separated by a colon. 

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.

When several ligands occur in the same complex, they are named in alphabetical order (ignore any numerical prefixes).
