1. Draw the structures of acetylacetonate and its resonance structure.
2. Structure of Mn(acac)3
3. Find out the magnetic moment of Mn(acac)3.
Charge of Mn3+ = +3
Total number of electron in Mn atom = 25
Number of electron in Mn3+ ion = 22
Eletron configuration of Mn3+ : [Ar] 3d4
μs = g √s(s+1)
= 2 √ 2(2+1)
