Question

What is coordination number of central metal ion in fe(c2o4)3?

Answer 1

6 As C2O4 is a bidentate ligand

Answer 2

The coordination number of central metal ion in $Fe(C_2O_4)_3$ is 6.

Explanation:

• Coordination number is defined as the number of coordinate bonds formed with the central metal atom/ions by surrounding complex.
• In the given coordination complex $Fe(C_2O_4)_3$ , the central metal atom is Fe and 3 atoms of $C_2O_4^-$ are surrounding it.
• As $C_2O_4^-$ is a didentate it donates two electrons to the metal atom to form bond due to which they occupy two positions around the central metal atom.
• As there are three ions of $C_2O_4^-$,  it will occupy = (2 × 3) = 6 positions around the central metal atom.
• Hence, the coordination number of iron in given complex is found to be 6.
