Comment: This structure is constructed based on the experimental (PEA)2PbBr4 published by Shibuya et al. (doi: 10.1107/S160053680903712X). This structure is the same as Data ID 1890 - however, the a axis is chosen as the out of plane axis and the supercell is doubled (out of plane) compared to the experimental structure and compared to Data ID 1890.
