Use the complexes [Fe(CN)₆]³⁻, [Mn(H₂O)₆]²⁺, [CoF₆]³⁻, [Mn(CN)₆]³⁻, [Fe(H₂O)₆]²⁺, [Co(NH₃)₆]³⁺, [Fe(CN)₆]⁴⁻ and [V(H₂O)₆]³⁺. Let P be the number of paramagnetic inner-orbital complexes, Q the number of paramagnetic outer-orbital complexes, R the number of paramagnetic low-spin complexes and S the number of paramagnetic high-spin complexes. Spin class applies to d⁴ to d⁷ ions only. Find (P + Q) − (R + S).
Answer:
1
Solution:
Paramagnetic inner-orbital: [Fe(CN)₆]³⁻, [Mn(CN)₆]³⁻, [V(H₂O)₆]³⁺, so P = 3. Paramagnetic outer-orbital: [Mn(H₂O)₆]²⁺, [CoF₆]³⁻, [Fe(H₂O)₆]²⁺, so Q = 3. Paramagnetic low spin: [Fe(CN)₆]³⁻ and [Mn(CN)₆]³⁻, so R = 2. Paramagnetic high spin: the three outer-orbital ones, so S = 3. (3 + 3) − (2 + 3) = 1.
