Question

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

K₄[Mn(CN)₆]

Answer 1

IUPAC name of the hybrid compound	Oxidation state of the central metal	Coordination number	Shape	Central metal ion	Electronic configuration	The value of n and the magnetic moment	Stereochemistry
Potassium hexacyanomangana te(II)	(+1) × 4 + x + 6 × (−1) = 0 ∴ x = +2	6	Octahedral	Mn2+	3d5, \[\ce{t^5_{2g}}\]	n = 1, `sqrt(1(1 + 2))` = 1.73 BM	Optically inactive
