Question
Write the hybridization type and magnetic behaviour of the complex [Ni(CN)4]2−. (Atomic number of Ni = 28)
Solution
Cyanide, CN− being a strong-field ligand causes the pairing up of valence electrons in the Ni2+ ion against the Hund's rule of maximum multiplicity. This results in the formation of an inner orbital complex, [Ni(CN)4]2− having diamagnetic character and dsp2 hybridisation.
