1. The problem statement, all variables and given/known data
I am confused about the heating of the unstable complex:
$[Fe(H_2O)_5(NO)]SO_4$
In one place I read that it gives $FeSO_4$ , whereas in other place it says $Fe_2(SO_4)_3$.
So which one is correct?

2. Relevant equations

3. The attempt at a solution
Thanks.
Any help appreciated.
