TL;DR: These materials retain a 3D character of their perovskite network despite incorporation of large HEA+ or TEA+ cations, demonstrating that the Goldschmidt tolerance factor can be bypassed and offer alternatives to reach the methylammonium- and bromine-free stable α-FAPI-type phase.

TL;DR: The description of perovskite networks through elimination/substitution processes from the ABX3 structure will be compared to the known dimensional reduction concept.

TL;DR: The prototype structure of (H3N(CH 2)2SS(CH2)2NH3)2I3BiI6====== fixme (1) can accommodate various changes according to the nature of the organic group, such as conformation, length or size as mentioned in this paper.

TL;DR: It was found that the high NH3 uptake is due to a combination of pore filling taking place below 150 h·Pa and chemisorption occurring at higher pressures and the latter process was shown to involve two phenomena: (i) coordination of NH3 molecules to Cd(2+) cations as follows from (113)Cd NMR and (ii) strong donor-acceptor interactions betweenNH3 molecules and pc1 ligands.

TL;DR: The dehydration of a iodobismuthate hybrid built up from Bi(4)I(16) clusters and protonated L-cystine molecules involves an unprecedented reversible dynamic structural change in the solid state leading to 1D BiI( 4) chains and 1D helical molecular chains, highlighting the templating effect of cations in the formation of iodobISMuthate network.
