Chemistry Question on coordination compounds

Which of the following complex has square planar structure?

A

[Ni(CN)4]2−\left[ Ni ( CN )_{4}\right]^{2-}

B

Ni(CO)4Ni ( CO )_{4}

C

[Zn(NH3)4]2+\left[ Zn \left( NH _{3}\right)_{4}\right]^{2+}

D

[NiCl4]2−\left[ NiCl _{4}\right]^{2-}

Answer

[NiCl4]2−\left[ NiCl _{4}\right]^{2-}

Explanation

Solution

Ni2+(d8)Ni^{2+}(d^{8}) : [Ni(CN)4]2−[Ni(CN)_{4}]^{2-} : ∴dsp2\therefore d s p^{2} hybridisation and square planer structure
