Chemistry Question on coordination compounds
Coordination number of Ni in [(C2O4)3]-4 is
A
3
B
6
C
4
D
2
Answer
6
Explanation
Solution
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.
