Question

k3[co(c2o4)3] iupac name
​

Answer 1

IUPAC name of $K_3[Co(C_2O_4)_3]$ is potassium trioxalato cobaltate (III)

Explanation :

Rules for naming of the coordination compounds :

The ligand named first then metal.

The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.

The ligands are named in alphabetical order before the metal ion.

Ligands that include a numerical prefix in the name use the prefixes bis for 2, tris for 3, or tetrakis for 4 to indicate their number.

If the complex ion is an anion, we drop the ending of the metal name and add –ate.

In the given coordination compound, Co is the cobalt metal, $C_2O_4$ are the ligands named as oxalato.

The charge on $[Co(C_2O_4)_3]$ is -3 and oxalate is having an oxidation state of -2.

$x+3(-2)=-3$

$x=+3$

Hence, the IUPAC name of $K_3[Co(C_2O_4)_3]$ is potassium trioxalato cobaltate (III)
