- type of hybridization
- magnetic moment value
- type of complex – inner, outer orbital complex

उत्तर
[Mn(CN)6]3-
Mn = [Ar]3d54s2
Mn3+ = [Ar]3d4
Mn (ground state)
Mn in +3 state
Mn in [Mn(CN)6]3-
d2sp3 hybridisation
xx are electrons donated by ligand CN-
Type of hybridization – d2sp3
Magnetic moment value – `sqrt(n(n + 2)) = sqrt(2(2 + 2))` = 2.87 BM ......(n = no. of unpaired electrons)
Type of complex – inner orbital
