Beyond templating: Electronic structure impacts of aromatic cations in organic–inorganic antimony chlorides

Abstract Organic cations influence the crystal packing and, less commonly, electronic structure of hybrid organic–inorganic materials. Two new compounds prepared from solution, (PEA)SbCl 6 and (PEA) 4 Sb 2 Cl 12 (PEA=phenylethylammonium), demonstrate how aromatic PEA cation modifies structures relative to inorganic antimony chlorides. In ethylammonium conformation results in a polar chiral structure, bandgap is characterized by organic‐inorganic charge transfer. mixed‐valence III V uniaxial elongation that analogs optoelectronic properties combine features intervalence transfer
