Novel layered sulfides of tin: synthesis, structural characterization and ion exchange properties of TMA-SnS-1, Sn3S7·(NMe4)2·H2O

Sn3S7·(NMe4)2·H2O has been shown to consist of the framework of composition [Sn3S7]2– with the two exchangeable [NMe4]+ ions occupying cavities in the structure; these molecules can be exchanged with a variety of alkali, alkali earth and transition metal cations.

Synthesis and structural characterization using synchrotron radiation of [(C6H13N2)2(H3O)(H2O)][AgGe4S10](dabco–AgGS–SB2): knitting sulfide metal clusters to form frameworks

A novel framework comprised of [Ge4S10]4– adamantine clusters linked by Ag+ is synthesized hydrothermally and its structure determined utilizing data collected on a 36 pl (36 × 10–12 l) single crystal using an X-ray synchrotron/imaging plate combination.

A novel antimony sulfide templated by ethylenediammonium

The structure of ethylenediammonium antimony sulfide, C 2 H 10 N 2 2+ .Sb 8 S 13 2- , is characterized by double chains of corner-linked SbS 3 pyramids. These chains contain openings formed by 16-membered rings, consisting of alternating Sb and S atoms, and interlock to form sheets in (001)

Trimethylammonium tin sulfide

The structure of trimethylammonium tin sulfide-water (1/0.72), [(CH 3 ) 3 NH] 2 [Sn 3 Sr].0.72H 2 O, consists of sheets with 24-membered ring openings containing alternating Sn and S atoms. Organic molecules resulting from the breakdown of the starting tetramethylammonium template reside between these sheets, which are stacked parallel to (001)

A one-dimensional germanium sulfide polymer akin to the ionosilicates: synthesis and structural characterization of DPA-GS-8, Ge4S9(C3H7)2NH2(C3H7)NH2(C2H5)

Ge4S9(C3H7)2NH2(C3H7)NH2(C2H5) consists of chains of corner-linked adamantane units with a composition of [Ge4S9]2– which are separated by two dipropylammonium (DPA) cations; the first reported chain-like structure of [Ge4S9]2–.
