Question
Explain the magnetic properties of [Ni(CN4)]2–.
Advertisements
Solution
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.
