Abstract

This study describes the synthesis of germanium and tin complexes Ge(mdpaS)₂ (1), Ge(edpaS)₂ (2), Ge(bdpaS)₂ (3), Ge(empaS)₂ (4), Sn(mdpaS)₂ (5), Sn(edpaS)₂ (6), Sn(bdpaS)₂ (7), and Sn(empaS)₂ (8) (mdpaSH = (Z)-N-methoxy-2,2-dimethylpropanimidothioic acid; edpaSH = (Z)-N-ethoxy-2,2-dimethylpropanimidothioic acid; bdpaSH = (Z)-N-(tert-butoxy)-2,2-dimethylpropanimidothioic acid; empaSH = (Z)-N-ethoxy-2-methylpropanimidothioic acid), using newly designed N-alkoxy thioamide ligands as precursors for metal chalcogenide materials. All complexes were characterized using various analytical techniques, and the single-crystal structures of complexes 5 and 7 revealed a distorted seesaw geometry in the monomeric SnL₂ 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 1–8 are potential precursors for group IV metal chalcogenide materials.

含 N-烷氧基硫酰胺配体的锗和锡卤化物材料前体

本研究描述了锗和锡配合物 Ge(mdpaS)2 (1)、Ge(edpaS)2 (2)、Ge(bdpaS)2 (3)、Ge(empaS)2 (4)的合成、Sn(mdpaS)2 (5)、Sn(edpaS)2 (6)、Sn(bdpaS)2 (7)和 Sn(empaS)2 (8)（mdpaSH = (Z)-N-甲氧基-2,2-二甲基丙脒硫酸；edpaSH = (Z)-N-ethoxy-2,2-dimethylpropanimidothioic acid；bdpaSH = (Z)-N-(tert-butoxy)-2,2-dimethylpropanimidothioic acid；empaSH = (Z)-N-ethoxy-2-methylpropanimidothioic acid），使用新设计的 N- 烷氧基硫代酰胺配体作为金属氢化物材料的前体。利用各种分析技术对所有配合物进行了表征，配合物 5 和 7 的单晶结构显示出单体 SnL2 的扭曲跷跷板几何形状。热重（TG）曲线显示，Ge 复合物和 Sn 复合物之间存在差异，前者表现出单步重量损失，而后者则表现出多步重量损失。因此，我们认为合成的配合物 1-8 是第四族金属卤化物材料的潜在前体。
