Write IUPAC name for each of the following and indicate oxidation state, electronic configuration and coordination number. Also give stereochemistry, magnetic moment :
`Cs[FeCl_(4)]`

Explanation

IUPAC name : cesium tetraachloridoferrate (III)
Coordination number of `Fe=1-x+4xx(-1)=0, x=+3`
Electronic configuration of `Fe^(3+)=3d^(5)=e^(2)t_(2)^(3)`
No. of unpaired electrons = 5,
Magnetic moment `=sqrt(5(5+2))=sqrt(35)=5.92BM`
