How many of the following complexes are both low spin and diamagnetic? [Co(en)₃]³⁺, [Fe(CN)₆]³⁻, [Fe(CN)₆]⁴⁻, [Mn(CN)₆]³⁻, [Co(NH₃)₆]³⁺, [CoF₆]³⁻, [Ru(bipy)₃]²⁺
Answer:
4
Solution:
Low-spin d⁶ complexes [Co(en)₃]³⁺, [Fe(CN)₆]⁴⁻, [Co(NH₃)₆]³⁺ and [Ru(bipy)₃]²⁺ are diamagnetic. [Fe(CN)₆]³⁻ (d⁵) and [Mn(CN)₆]³⁻ (d⁴) are low spin but paramagnetic. [CoF₆]³⁻ is high spin. Count = 4.
