What is the spin-only magnetic moment, in BM, of the complex ion in $K X_{3} [Mn (CN) X_{6}]$ ? Treat CN- as strong field. Give the answer to two decimal places.

Numerical answer type, answer in BM, tolerance 0.01.

Charge:

x - 6 = - 3

gives Mn(III),

d^{4}

. Strong-field CN- gives

t_{2 g}^{4} e_{g}^{0}

with 2 unpaired electrons.

μ = 2 \times 4 = 8 = 2.83 BM
