The crystal field energy-level diagram for a square pyramidal complex (ML₅) is known to be intermediate between an octahedral complex (ML₆) and a square planar complex (ML₄).



Does the crystal field energy-level diagram below correspond to a square pyramidal, ML₅, complex with one ligand along the ±z-axis, two along the ±x-axis, and two along the ±y-axis?

• A. Yes, it does correspond to the crystal field energy-level diagram of a square pyramidal complex (ML₅) with one ligand along the ±x-axis, two along the ±y-axis, and two along the ±z-axis.
• B. No, it does not correspond to the crystal field energy-level diagram of a square pyramidal complex (ML₅) with one ligand along the ±x-axis, two along the ±y-axis, and two along the ±z-axis.

Answer: (A)
