Question

The structure of paramagnetic nickel complex, $[NiCl_4]^{2-}$ is

• A. tetrahedral
• B. square planar
• C. trigonal bipyramidal
• D. distorted octahedral

Answer 1

Answer: (A)

tetrahedral

Answer 2

In $[Ni(Cl)_4]^{2-}$ complex ion, $Ni$ is in $+2$ oxidation state. It has electronic configuration $3d^8$. It is paramagnetic and $sp^3$ hybridised so the four hybridised equivalent orbitals oriented tetrahedrally
