Solution

K₄[Mn(CN)₆]

Potassium hexacyanomanganate(II)

Oxidation state of manganese = +2

Electronic configuration: d⁵⁺: t₂_g⁵

Coordination number = 6

Shape: octahedral.

Streochemistry: optically inactive

Magnetic moment, μ = ` sqrt(n(n+2))`

`=sqrt(1(1+2))`

`=sqrt3`

=1.732 BM

Concept: Nomenclature of Coordination Compounds - Formulas of Mononuclear Coordination Entities
