Nomenclature of Coordination Compounds

      Unable to write the nomenclature of coordination compounds? Here is an easy format to go through and learn how to name the coordination compounds correctly in a very less time..  
 1.      The ligand part is named first then the positive central metal atom is  named.

       2.      In the coordination sphere the name of the ligands is written alphabetically regardless of their charge followed by the metal.  

        Eg:- if the attached ligands are  (amine) and (aqua)  then first preference must be given to  as alphabetically amine comes before aqua.

      3.    
            a)The name of the negative ligands ends with “-O”

              

           

          

            

          

         

          

          

           

       

       

       

            

           

         

         

         

            

    b)Neutral Ligands:

    

     

   

     

      

  

  

     c)Positive Ligands ends with - ium:

         

                 

                 

    4. The oxidation state of the central metal atom is shown by a roman numeral enclosed in brackets immediately following its name.

    5. Complex cations and neutral molecules have no special ending, but complex anions ends with “-ate”.

Example:

   6.In case of ambidenate ligands after the name of the ligand-Name of the atom through which it is attached to the central metal atom is written.

 Example:

   7.In case of bridged ligand the bridged ligand is shown by the symbol  "" attached to metal atom.

EXAMPLE :

    

        8.     While writing the name of complex don’t give spaces and write it in a single line without spaces .
