Question

Explain the magnetic property of [Ni (CN)4]2-​

Answer 1

Answer:

Magnetic properties of [Ni(CN4)]2–:

In [Ni(CN4)]2– ion, Ni2+ undergoes dsp2 hybridization. Four vacant dsp2 hybrid orbitals of Ni2+ overlap with four orbitals of CN– ions to form Ni–CN coordinate bonds. Configuration after the complex formation becomes: The complex has no unpaired electrons and hence, diamagnetic.
