Question
Give the electronic configuration of d⁸ and d⁹ complexes in both weak and strong fields. Also calculate their CFSE.
Answer :
Word Count : 252
For octahedral fields, the d-orbital set splits into t2g (−0.4Δo each) and eg (+0.6Δo each). For d⁸ in either weak- or strong-field octahedral complexes the electronic configuration is t2g⁶eg². Hence CFSE = (6 × −0.4Δo) + (2 × +0.6Δo) = −2.4Δo + _________ _________ _______ ___ _________ _________.
