Question

Consider the complex : K₃[Co(C₂O₄)₂Cl₂]

The coordination number, the oxidation number of Co and the number of unpaired electrons on the metal are respectively

medium

Solution

Correct option is

6, +3, 4

is bidentate and Cl^– is monodentate ligand.

Hence, C.N. = 2 × 2 + 2 × 1 = 6

Both and Cl^– are weak field ligands and hence form outer (high spin) complex.

Co(III) : 3d⁶ (n = 4)
