Hybridisation and geometry of [Ni(CN)_4]^ 2- are

Hybridisation and geometry of $\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$ are

Step-by-step solution

$\operatorname{In}\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}, \mathrm{Ni}^{2+}=3 d^8 4 s^0\mathrm{AsCN}^{-}$ is a strong ligand, pairing of electrons take place, Therefore, $d s p^2$ hybridisation gives square planar geometry.
