What can be inferred from the magnetic moment values of the following complex species?

Explanation

`Mn^(2+) : 3d^5` , magnetic moment of 2.2 indicates that it has one unpaired electron and hence forms inner orbital or low spin complex. Its configuration is : ` t_(2g)^5`
`[Fe(H_2O)_6]^(2+)`
`Fe^(2+) : 3d^6` , The magnetic moment value is close to 4 unpaired electrons. So it forms outer orbital complex having 4 unpaired electrons. Its configuration is : `t_(2g)^4 e_g^2`
`K_2[MnCl_4]`
`Mn^(2+) : 3d^5` ,
The magnetic moment corresponds to 5 unpaired electrons. The d-orbitals are not disturbed. So it forms tetrahedral complex. Its configuration is : ` e^2 t_2^3`
