Question

The structures of $\left[Ni{\left(CO\right)}_4\right]$ and $\left[Ni{\left({\left(P{h}_3\right)}_{3}P\right)}_{2}C{l}_2\right]$ are:

• A. square planar in both cases
• B. tetrahedral and square planar respectively
• C. tetrahedral in both cases
• D. square planar and tetrahedral respectively

Answer 1

The correct option is C tetrahedral in both cases

1) $\left[Ni{\left(CO\right)}_4\right]$: $Niin{d}^{10}$ configuration and $s{p}^3$ hybridization, low spin complex and tetrahedral structure.
2) $\left[Ni{\left({\left(P{h}_3\right)}_{3}P\right)}_{2}C{l}_2\right]$: $N{i}^{+2}in{d}^8$ configuration and $s{p}^3$ hybridization, high spin complex and tetrahedral structure.
