Which one of the following complexes in an outer orbital complex?

Accepted Answer

Hybridisation

\underset{d^{2} s p^{3}}{{[F e {(C N)}_{6}]}^{4 -},} \underset{d^{2} s p^{3}}{{[M n {(C N)}_{6}]}^{4 -},}

\underset{d^{2} s p^{3}}{{[C o {(N H_{3})}_{3}]}^{3 +},} \underset{s p^{3} d^{2}}{{[N i {(N H_{3})}_{6}]}^{2 +}}

Hence

{[N i {(N H_{3})}_{6}]}^{2 +}

is outer orbital complex.
