A perovskite CH3NH3+PbI3- (ABI3 type) is proposed to crystallise in Orthorhombic (space group no. 140: I4/mcm) lattice. Is there any way to drive the coordinates of each species in the unit cell (other than using cif file) ?
If space group is known and lattice parameters are also known for a ABO3 system. Is there any way theoritically and experimentally that one can find the coordinates of each A, B and O in the unit...
