Interpretation Introduction

Interpretation:

The formula of the given compound has to be written.

Concept Introduction:

IUPAC nomenclature of coordination compounds:

• Just as in naming simple salts, if the compound is a salt, name the cation first and then the anion.  For example, ${\text{K}}_{\text{3}}\left[\text{Fe}{\left(\text{CN}\right)}_{\text{6}}\right]$ is potassium hexacyanoferrate $\left(\text{III}\right)$.
• In naming a complex ion or a neutral complex, name the ligands first and then the metal.  The names of anionic ligands end in -o.  They are usually obtained by changing the anion endings -ide to -o and -ate to -ato.  Neutral ligands are specified by their usual names, except for ${\text{H}}_{\text{2}}{\text{O, NH}}_{\text{3}}\text{, and CO}$, which are called aqua, ammine, and carbonyl, respectively.  The name of a complex is one word, with no space between the various ligand names and no space between the names of the last ligand and the metal.
• If the complex contains more than one ligand of a particular type, indicate the number with the appropriate Greek prefix: di-, tri-, tetra-, penta-, hexa-, and so forth.  The ligands are listed in alphabetical order, and the prefixes are ignored in determining the order. Thus, tetraaqua precedes dichloro in the name for $\left[\text{Cr}{\left({\text{H}}_{\text{2}}\text{O}\right)}_{\text{4}}{\text{Cl}}_{\text{2}}\right]\text{Cl}$: tetraaquadichlorochromium $\left(\text{III}\right)$ chloride.
• If the name of a ligand itself contains a Greek prefix-for example, ethylenediamine - put the ligand name in parentheses and use one of the following alternative prefixes to specify the number of ligands: bis- (2), tris- (3), tetrakis- (4), and so forth.  Thus, the name of $\left[\text{Co}{\left(\text{en}\right)}_{\text{3}}\right]{\text{Cl}}_{\text{3}}$ is tris(ethylenediamine)cobalt $\left(\text{III}\right)$ chloride.
• Use a Roman numeral in parentheses immediately following the name of the metal to indicate the metal’s oxidation state.
• In naming the metal, use the ending -ate if the metal is in an anionic complex.  Thus, ${\left[\text{Fe}{\left(\text{CN}\right)}_{\text{6}}\right]}^{\text{3-}}$ is the hexacyanoferrate $\left(\text{III}\right)$ anion.
