Abstract: Exploring orange-light-emitting lead-free halides with high photoluminescence quantum yields (PLQYs) is a significant challenge in luminescent materials research. Herein, a zero-dimensional organic–inorganic hybrid halide, namely, 4,4′-(ethane-1,2-diyl)dipyridin-1-ium pentachloridoantimonate(III), (C 12 H 14 N 2 )[SbCl 5 ] or [H 2 bpa][SbCl 5 ], where bpa is 1,2-bis(pyridin-4-yl)ethane, was synthesized via acid solution evaporation. The compound crystallizes in the triclinic space group P 1 . The asymmetric unit consists of an [SbCl 5 ] 2− anion and two half [H 2 bpa] 2+ cations. The [SbCl 5 ] 2− anion and [H 2 bpa] 2+ cations are linked via intermolecular hydrogen bonds and π–π interactions to form a three-dimensional supramolecular architecture. Significantly, this halide exhibits highly efficient orange-light emission centred at 600 nm, with a PLQY of 65.57%.
