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