Question

Quizplus · Accepted Answer

In square planar Ni(CN)₄^2- complex ion, Ni2+ has an electronic configuration of [Ar]3d8. Ni2+ first uses its 4s and 4p orbitals to hybridize into four hybrid orbitals of dsp². Then, four pairs of electrons from four ligands of CN groups and two sulfur atoms donate to the empty hybrid orbitals of Ni. Finally, the hybridization pattern is dsp².
