    Coordination number of \[Ni\] in \[{{[Ni{{({{C}_{2}}{{O}_{4}})}_{3}}]}^{4-}}\]is

    A)  3                 

    B)  6

    C)  4                  

    D)  5

    Correct Answer: B

    Solution :

     Coordination number of \[Ni\] in \[{{[Ni{{({{C}_{2}}{{O}_{4}})}_{3}}]}^{4-}}\]is 6. This is because \[{{C}_{2}}O_{4}^{2-}\] (oxalate) is a bidentate ligand and thus, each coordinated with the central atom at two sites.
