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-) `
Tetrachloridomanganate (II) ion . Electronic configuration of ` Mn=z25` is `3d^(5) 4s^(2) ` Mn is ground state
` (##SUR_CHE_XII_V01_C05_E03_005_S01.png" width="80%">
Oxidation state of Mn in the complex is ` MN^(+2)`
` Mn^(2+) ` in the complex `[MnCl_4) ^(2-) `
` (##SUR_CHE_XII_V01_C05_E03_005_S02.png" width="80%">
` Cl^(-) ` is weak field ligand so no pairing occurs. hybridisation is `sp^(3)` so the geometry of the complex tetrahedral.
