Coordination Compounds

Question

Wired Faculty App

Give the oxidation state, d-orbital occuptaion and coordination number of the central metal ion in the following complexes:
[Mn(H₂O)₆SO₄

Solution

The central metal ion is Mn.
The coordination number is 6.
Water is neutral ligand thus oxidation state is:

X+0 =+2
X= +2

Oxidation state = +2
d-orbital occupation is $d^{5} (t_{2 g}^{3} e {_{g}}^{2})$
