(C5H9N2)[BiI4]: A One-Dimensional Bismuth-Based Organic-Inorganic Hybrid Material for Fast Rhodamine B Degradation Under Dark Condition

Lead-free organic-inorganic hybrid materials have attracted wide interest due to their excellent optoelectronic and photovoltaic properties. Herein, we synthesized a Bi-based hybrid material with one-dimensional (1D) Bi-I anionic chains, namely, (C5H9N2)[BiI4] (1) by solvothermal method. Single-crystal X-ray diffraction analysis reveals that it crystallizes in monoclinic space group of C2/c with the cell parameters a = 15.539(13) angstrom, b = 13.860(12) angstrom, c = 7.789(6) angstrom, beta = 117.02(2)(o), V = 1494(2) angstrom(3), and Z = 4, which is composed of protonated 1,3-dimethylimidazolium cations and one-dimensional (1D) [BiI4](infinity)(-) chains interconnected via edge-sharing mu(2)-I. This compound exhibits fast degradation of rhodamine B (RhB) at room temperature under dark condition.
