N2 - We report the crystal structures, thermal stability, and luminescence properties of three trimethylsulfonium halocuprates: (TMS)Cu2I3, and two new bromide phases: (TMS)Cu2Br3 and (TMS)2CuBr3. (TMS)Cu2I3 and (TMS)Cu2Br3 are isostructural and contain double chains of edge-sharing [CuX4] tetrahedra, whereas (TMS)2CuBr3 features isolated [CuBr3]2− triangular units. All compounds exhibit direct bandgaps and demonstrate photoluminescence at low temperature, with (TMS)Cu2Br3 demonstrating temperature-dependent dual emission behavior, observed for the first time among related hybrid halocuprates. Through comparative analysis of optical properties with structurally related halocuprates and DFT calculations, we elucidate the structure–property relationships governing the observed luminescence behavior of ACu2X3-type halocuprates.
