${\text{}}_{\text{28}}\text{Ni}$has$\text{+2}$oxidation state and since the complex is Diamagnetic, all electrons are paired in inner 3d, orbital to provide the electronic configuration as under:



${\text{L}}^{-}$might have been a strong field like${\text{CN}}^{-}.$Hybridisation is${\text{dsp}}^{\text{2}}\text{.}$Number of unpaired electrons =$\text{0}$
