Crystal structures of (a) Cs2AgBiBr6 and (b) (BA)4AgBiBr8. Ball and stick models showing the bond lengths (in Å) and in-plane connectivity of [BiBr6] and [AgBr6] octahedra for (c) Cs2AgBiBr6 and (d) (BA)4AgBiBr8. Bond angles of MI − X − MIII for (e) Cs2AgBiBr6 and (f) (BA)4AgBiBr8. The black, white, purple, blue, yellow, green, and pink balls refer to C, H, N, Cs, Bi, Ag, and Br atoms, respectively. Calculated electronic band structure and atomic orbital projected density of states (PDOS) of (g) Cs2AgBiBr6 and (h) (BA)4AgBiBr8. Source data are provided as a Source Data file.
