Calling double perovksites using MPrester

Dear All,

I am working on Perovskites. I have extracted ABO3 compounds with their properties like (‘pretty_formula’, ‘e_above_hull’, ‘spacegroup’) using MPrester with following command:

Sparks_API = 'L64O7l0RBG9wtrze’
from pymatgen.ext.matproj import MPRester
mpr = MPRester(Sparks_API)
**single_O = mpr.query('O3’,[‘pretty_formula’, ‘e_above_hull’, ‘spacegroup’])

Now I am trying for double Perovskites like (e.g. AA’BB’O6, A2BB’O6, A2B2O6). I started with AA’BB’O6 with following command but it run for infinite time and did not produce any outcome after a long while…

Sparks_API = 'L64O7l0RBG9wtrze’
from pymatgen.ext.matproj import MPRester
mpr = MPRester(Sparks_API)
**single_O = mpr.query(’**O6’,[‘pretty_formula’, ‘e_above_hull’, ‘spacegroup’])

Any specific requirement for extracting this are required. Please suggest with your valuable points.

Thanking you
