The crystal field splitting energy (CFSE) for C o C l 6 4 - is about 18000 c m - 1 . What would be the CFSE value for [ C o C l 4 ] 2 - ?

Correct answer

8000

Step-by-step solution

CFSE Δ 0 of [ C o C l 6 ] 4 - = 18000 c m - 1 CFSE Δ t of [ C o C l 4 ] 2 - = ? From formula, Δ t = 4 9 × Δ 0 = 4 9 × 18000 c m - 1 = 8000 c m - 1
