Hello dear all. Please, how do I represent the  A-site mixed occupancy of  1.1 Nitrogen, 1 Carbon and 6 Hydrogen Atoms in the I4cm Tetragonal MA₀.₉₅GA₀.₀₅PbI₃ Crystal Structure knowing that no fractional atoms exist in a single unit cell? 

In fact I want to see the effect of GA composition when mixed with MA cation in MAPbI3... So I will need to do that process a couple of time when changing the GA proportion into the A-site cation of perovskite.

Your help will be highly appreciated
