This is #Fe^(3+)# ion.........., i.e. #"ferric ion, Fe(III)"#

Explanation:

#[Fe(C-=N)_6]^(3-)# is the complex ion, that is composed of a #Fe^(3+)# centre, and #6xx""N-=C^(-)# ligands.

Of course, the resultant complex preserves the ionic charge of its consituent ligands and metal centre, and the net charge is #6xx(-1)+3=??#

If the counterion were potassium, i.e. #K^+#, what salt would likely precipitate from solution?
