For Mo2N3 N would need to be -2 oxidation state and that is highly unlikely. N has usual oxidation states of -3, +3, and +5. Mo has several including 2,3,4,5, and 6.
For PbO2, we usually write the empirical formula unless there is evidence that it exists in some other form; i.e., HO is the empirical formula for hydrogen peroxide BUT we know it exists as H2O2 and we write it the way it exists.
