Question

What are the values of $m+n$ in the anionic species $\left[Ti\right(CO{)}_m{]}^{n-}$, if it is following sidwick EAN rule and having octahedral shape.

Answer 1

$\left[Ti\right(CO{)}_m{]}^{n-}$
$\Rightarrow$ For octahedral shape of complex; $m=6$
$\Rightarrow E.A.N.ofTi=36\Rightarrow 22+n+12=36\Rightarrow n=2$
So, $m+n=8$
