Which of the following is a low-spin complex? A) [Ni(CN)₄]²⁻ B) [Mn(H₂O)₆]²⁺ C) [CoF₆]³⁻ D) [NiCl₄]²⁻ E) [CoI₄]²

Question

Quizplus · Accepted Answer

Low-spin complexes are typically formed with strong field ligands, such as cyanide (CN−), which cause a large splitting in the d-orbital energy levels, leading to the pairing of electrons in the lower energy orbitals before any are placed in the higher energy orbitals. [Ni(CN)4]2− is an example of a low-spin complex due to the presence of the strong field cyanide ligands.
