Question

From crystal field theory , find out the number of unpaired electrons in the low - spin complex [Co(CN)6]3-

Answer 1

SOLUTION :-


1) The complex has an octahedral shape
The aqua ligand (H2OH2O) is typically regarded as weak-field ligand.

2) The d electron configuration for CoCo is d6d6

3) The splitting energy is small.

Therefore, the complex is expected to be high spin.
