[AgPb2I3(OH)2]: An unprecedented quaternary heterometallic semiconducting framework synthesized under ionothermal condition

•Ionothermal synthesis of crystalline inorganic materials•Unprecedented quaternary Ag–I–Pb–OH heterometallic framework•[Pb4(OH)4] cubane and [Ag2I6] dimeric building blocks•Remarkable luminescence and tuneable semiconducting properties

We reported herein an unprecedented quaternary heterometallic framework, namely, [AgPb2I3(OH)2] (1), which was successfully produced under ionothermal condition. In the title compound, [Pb4(OH)4] cubane and [Ag2I6] building blocks are jointed together to give a (6,6)-connected pcu topology. Compound 1 shows not only remarkable luminescent emissions, but also semiconducting properties tuned by the corresponding metal halide components.
