Hydrothermal syntheses and characterization of two tetramethylammonium templated indium sulfides

• The 3D open framework of [(Me)4N]6[In10S18] has large porosity.
• The double-layered structure of [(Me)4N]13[Cu5In30S54] is built from T5 clusters.
• [(Me)4N]+ cation exhibits strong structure-directing effect for indium sulfides.

Two indium sulfides [(Me)4N]6[In10S18] (1) and [(Me)4N]13[Cu5In30S54] (2) have been hydrothermally synthesized. Compound 1 is a 3D open framework built from T3 clusters, which has large porosity. Compound 2 has a double-layered structure constructed by T5 clusters. Our results indicate that tetramethylammonium ion is an efficient structure-directing agent for both ternary and quaternary indium sulfides. The optical and thermal properties have also been investigated.

Two indium sulfides have been hydrothermally synthesized in the presence of tetramethylammonium ion as structure-directing agent.Figure optionsDownload as PowerPoint slide
