The coordination number of the central metal ion in
[Co(C₂O₄)2(OH)₂]⁻³ exists 6.
The quantity of neutral atoms or ions encircling the main metal atom is known as the coordination number.
In given case there are four ligands surrounding the Co central atom.
1) Oxalate Ion:
The ion of oxalate has two negative charges (shown below). Therefore, each oxalate forms two coordinate covalent connections with a metal atom in the middle and four coordinate covalent bonds with two Oxalate Ions.
2) Hydroxyl Ion:
One negative charge exists on the hydroxyl ion. As a result, it forms a covalent bond with a Co atom.
The coordination number of the central metal ion in
[Co(C₂O₄)2(OH)₂]⁻³ exists 6.
