Question

Which complex has square planar structure?
a) [Ni(CO)₄]b) [NiCl₄]²⁻c) [Ni(CN)₄]²⁻d) Fe(CO)₅]

Answer 1

option "c" is correct....

Answer 2

c) [Ni(CN)₄]²⁻ is the correct answer.

Cyanonickelates is the class of chemical compound containing the anions with the Nickel Atoms, and Cyanide Groups.

Most important that these are the tetracyanonickelates containing four cyanide groups per nickel.

The tetracyanonickelates contain the [Ni(CN)4]2− Anion.

In the formation of [Ni(CN)₄]²⁻, the type of hybridisation involved Formation Of Nicn The Type Of Hybridisation.
