The spin only magnetic moments of Tetrachloridomanganate (II) ion is 5.9 BM. On the basis of VBT , predict the type of hybridisation and geometry of the compound.

Explanation

`[MnCl_(4)]^(2-)`
Electronic configuration of Mn atom
Electronic configuration of `Mn^(2+)` ion
Hybridisation and formation of `[MnCl_(4)]^(2-)` complex
`Cl^(-)` is weak field ligand no electrons pairing occurs.
`** sp^(3)` hybridistion
`**` It has 5 unpaired electrons. Hence paramagnetic
`**` Magnetic moment,
`mu_(s)=sqrt(n(n+2))BM`
`n=5`
`mu_(s)=sqrt(5(5+2))=sqrt(5(7))`
`sqrt((35))=5.9BM`
`**` It has tetrahedral geometry.
