Oxidation number -

It is represented by roman numeral in parenthesis following the name of coordination entity.

- wherein

Eg. [Cu(CN)_4]^2^-

x-4 = -2

x= 2

Structure 

No.of CO-CO bond =1 

No. of Bridging carbon =2

 

  

 

Crystal Field Theory -

According to this theory, metal and ligand are considered as point charges. This theory deals with electrostatic force of attraction means the talks about the ionic character of M-L bond. 

-

 

 

 

Complex Salt -

Do not dissociate completely when disssolved in water

- wherein

eg: K_{4}\left \left [ Fe\left (CN \right )_{6} \right ]\rightarrow 4K^{+}\left [ Fe\left ( CN \right )_{6} \right ]^{4-}

But do not give Fe^{2+} and  CN^{-} 
ions
