Question

Zero magnetic moment of octahedral k2nif6 is due to flurdo is a weak field ligand

Answer 1

I'm so sry but I'm not sure bat the answer but I guess its not true

Answer 2

Answer:

The zero magnetic moments of octahedral $K_2 NiF_6$ are thanks to the low spin $d^6 Ni(IV)$ complex.

Explanation:

The oxidation number, or number, is the hypothetical charge of an atom if all of its bonds to different atoms were fully ionic.

Firstly, we are going to find the number.

As we know $[NiF_6]$ has $2-$ oxidation.

So, $[NiF_6]^{2-}$ is

$\begin{aligned}x-6&=-2\\ x&=4\end{aligned}$

In $+4$ the oxidation number, fluoride also behaves as a robust field ligand.

Therefore, there's an occasional spin of  $d^6 Ni(IV)$ the complex.

So, there are not any paired electrons all are unpaired electrons.

Thus, the magnetic moment of non-paired electrons is zero.
