The species [RhCl₆]^{3 -} is considered a strong field, low spin complex. Which statement below is true regarding this complex?

Question

Quizplus · Accepted Answer

A strong field ligand will cause the pairing of electrons in the d orbitals of the metal ion, leading to a low spin complex with no unpaired electrons. The complex has six ligands (two chloride ions and two bidentate thiolate ligands), so there are 6 * 2 = 12 electrons donated to the metal ion. The metal ion has a +3 charge, so it has lost three electrons from its neutral state. Therefore, the electronic configuration of the metal ion is d^6, and pairing of electrons in the d orbitals gives a d^6 configuration with no unpaired electrons, which is consistent with option C.
