Answer

$\ce{K_4[Mn(CN)_6]} \ \text{IUPAC}$ name: Potassium hexacyanomanganate $(II)$.
Oxidation state of manganate $= +2$ Electronic configuration of $d^{5+} : t_{2g}^5$ Coordination number $= 6$ Shape:
: octahedral. Stereochemistry: optically inactive Magnetic moment:µ$=\sqrt{\text{n}(\text{n}+2)}$
$=\sqrt{1(1+2)}$
$=\sqrt{3}$
$=1.732$
