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 in Brief

Solution

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
