资源简介：
The main goal of this proposal is to advance the understanding of the largely unexplored Cs- and Rb-containing bismuth halides. We will study the monoclinic structure of Rb3Bi2Br9, only reported once before, and possible phase transitions suggested by DSC experiments. We will also combine the obtained results with neutron diffraction data to perform a detailed study of the electron density, studying thoroughly the Bi3+ lone pair, as well as its influence on the monoclinic distortion and its evolution with temperature.
