Germanium and Tin Precursors for Chalcogenide Materials Containing -Alkoxy Thioamide Ligands. | LitMetric
This study describes the synthesis of germanium and tin complexes Ge(mdpaS) (), Ge(edpaS) (), Ge(bdpaS) (), Ge(empaS) (), Sn(mdpaS) (), Sn(edpaS) (), Sn(bdpaS) (), and Sn(empaS) () (mdpaSH = ()--methoxy-2,2-dimethylpropanimidothioic acid; edpaSH = ()--ethoxy-2,2-dimethylpropanimidothioic acid; bdpaSH = ()--(tert-butoxy)-2,2-dimethylpropanimidothioic acid; empaSH = ()--ethoxy-2-methylpropanimidothioic acid), using newly designed -alkoxy thioamide ligands as precursors for metal chalcogenide materials. All complexes were characterized using various analytical techniques, and the single-crystal structures of complexes and revealed a distorted seesaw geometry in the monomeric SnL form. Thermogravimetric (TG) curves showed differences between Ge compounds, which exhibited single-step weight losses, and Sn compounds, which exhibited multistep weight losses. As a result, we suggest that the synthesized complexes - are potential precursors for group IV metal chalcogenide materials.
