Step-by-step solution

$( P ) {\left[Fe{F}_{6}\right]}^{4 -}$

$( Q ) \left[Ti{\left({H}_{2}O\right)}_{3}C{l}_{3}\right]$

$\left(R\right) {\left[Cr{\left(N{H}_{3}\right)}_{6}\right]}^{3 +}$

$( S ) {\left[FeC{l}_{4}\right]}^{2 -}$

$\left(T\right) \left[Ni{\left(CO\right)}_{4}\right]$
$Ni: 3{d}^{8}e{S}^{2}$

Back pairing of elements due to pressure of strong field ligand

$( U ) {\left[Ni{\left(CN\right)}_{4}\right]}^{2 -}$
$N{I}^{2 +}: 3{d}^{8}$
