Synthesis and single-crystal structure of sodium sulfide cationic cluster in the sodalite cavity of zeolite Y (FAU, Si/Al = 1.56)

The extraframework sodium sulfide cationic cluster, Na 4 S 2+ , has been introduced into zeolite Y (FAU, Si/Al = 1.56). A single crystal of |Na 73 (Na 4 S 2+ ) 1.0 |[Si 117 Al 75 O 384 ]-FAU was prepared by allowing aqueous 0.1 M Na 2 S solution to flow past a |Na 75 |[Si 117 Al 75 O 384 ]-FAU cryst...
