Question

Write the IUPAC names of the follow Co-ordination compounds.
`K_(3)[Fe(C_(2)O_(4))_(3)]`

Answer 1

Let the oxidation state of Fe is x.
`(+1)3+x+(-2)3=0" "[because" Oxalate ion "(C_(2)O_(4)^(2-))` bears-2 charge.]
`3+x-6=0, x=+3`
So, the name of the complex is potassium trioxalateferrate (III)
