[((R)-C₈H₁₂N)₄][Bi₂Br₁₀] and [((S)-C₈H₁₂N)₄][Bi₂Br₁₀]: Chiral Hybrid Bismuth Bromides Templated by Chiral Organic Cations.

ABSTRACT: Single crystals of organically templated chiral bromobismuthates(III), [((R/S)-C₈H₁₂N)₄][Bi₂Br₁₀], have been grown for the first time via a slow evaporation method. Each of the chiral molecular compound consists of (R) or (S)-1-phenylethylammonium ([C₈H₁₂N]⁺) cations and [Bi₂Br₁₀]^4- anions. Both the title compounds reveal thermal and moisture stabilities up to ca. 220 °C and over 1 month, respectively. The newly prepared Bi³⁺-based organic-inorganic hybrid materials show optical band gap of ca. 2.88 eV. The noncentrosymmetric [((R)-C₈H₁₂N)₄][Bi₂Br₁₀] and [((S
