Which of the following shall form an octahedral complex ?
Answer»
`d^(4)` (LOW spin) `d^(8)` (high spin) `d^(6)` (low spin) All of these
Solution :In `d^(6)` (low spin), electrons PAIR up thereby making two empty d-orbitals available for `d^(2)sp^(3)` hybridisation as in the CASE of `[FE(CN)_(6)]^(4-)`
