Comparison studies of hybrid lead halide [MPb2X7]2− (M = Cu, Ag; X = Br, I) chains: band structures and visible light driven photocatalytic properties

A series of inorganic–organic hybrid heterometallic halides of [TM(2,2-bipy)₃]MPb₂X₇ (M = Ag/Cu, X = Br, I) have been solvothermally prepared with visible light driven photocatalytic properties.
