Give the electronic configuration of the following complexes on the basis of Crystal field splitting theory. [CoF_(6)]^(3-),[Fe(CN)_(6)^(4-) and [Cu(NH_(3))_(6)]^(2+)

Answer»

Solution :Electronic configuration of the COMPLEXES on the BASIS of CFST are given as under :
`[CoF_(6)]^(3-),Co^(3+)(d^(6))t_(2g)^(4),e_(g)^(2)`
`[Fe(CN)_(6)]^(4-), Fe^(2+)(d^(6)) t_(2g)^(6), e_(g)^(0)`,
`[Cu(NH_(3))_(6)]^(2+),Cu^(2+),Cu^(2+)(d^(9))t_(2g)^(6),e_(g)^(3)`
