# Write down the IUPAC name for each of the following complexes and indicate the oxidation state, electronic configuration and coordination number. Also give stereochemistry and magnetic moment of the complex: K4[Mn(CN)6] - Chemistry

Write down the IUPAC name for each of the following complexes and indicate the oxidation state, electronic configuration and coordination number. Also give stereochemistry and magnetic moment of the complex:

K4[Mn(CN)6]

#### Solution

K4[Mn(CN)6]

Potassium hexacyanomanganate(II)

Oxidation state of manganese = +2

Electronic configuration: d5+t2g5

Coordination number = 6

Shape: octahedral.

Streochemistry: optically inactive

Magnetic moment, μ =  sqrt(n(n+2))

=sqrt(1(1+2))

=sqrt3

=1.732 BM
