What type of geometry and magnetic nature is present in a complex [ NiCl ₄ ]^ 2-?
Options
- ASquare planar, diamagnetic
- BSquare planar, Paramagnetic
- CTetrahedral, Paramagnetic
- DTetrahedral, diamagnetic
Correct answer
C. Tetrahedral, Paramagnetic
Step-by-step solution
As Cl ⁻ is a weak field ligand, therefore outer hybridization takes place and [ NiCl ₄ ]⁻² has tetrahedral geometry and paramagnetic character.
