Consider that a d⁶ metal ion () forms a complex with aqua ligands, and the spin only magnetic moment of the complex is 4.90 BM. The geometry and the crystal field stabilization energy of the complex is :

Answer: (B)

Solution

With 4 unpaired electrons the d⁶ aqua complex is high spin; the paper's working gives CFSE = −0.4 Δ₀ for the
