Description
In our recent investigation on MAPbCl3, we found that phase separation occurs in the orthorhombic low-temperature phase, depending on the graining intensity. For lightly ground batches, besides the orthorhombic phase "o1" (space group Pnma, a ≈ 11.2 Å, b ≈ 11.3 Å, c ≈ 11.3 Å) another orthorhombic phase "o2", which has the same space group Pnma as "o1", but a smaller crystal lattice (a ≈ 8.0 Å, b ≈ 11.3 Å, c ≈ 7.9 Å) was observed by us.
