Abstract

We report a simple synthesis of a new lead-free zero-dimensional (0D) hybrid halide compound, (5P1)InBr₅·2H₂O [(5P1) = NH₃C₆H₁₂NH₃], which hosts isolated and distorted octahedra of [InBr₅(H₂O)]²⁻, surrounded by bulky asymmetric organic cations [(5P1)²⁺] and H₂O molecules. The hybrid crystals exhibit broad self trapped excitonic (STE) emission due to strong anharmonic soft structure.
