Coordination number of Ni in [(C2O4)3]-4 is
Coordination number of Ni in [(C2O4)3]-4 is
3
6
4
2
The Correct Option is B
Solution and Explanation
The correct option is (B):6.
The coordination number of Ni in [Ni[(C2O4)3]-4 is 6. This is due to the bidentate nature of C2O3-4 ligands, and there are three such ligands present. Therefore, the coordination number is calculated as 2 (bidentate) x 3 (ligands) = 6.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
