The four compounds, namely: 5-nitro-2-furaldehyde thiosemicarbazone (1); 5-nitro-2-thiophene thiosemicarbazone (2); 5-nitro-2-furaldehyde semicarbazone (3); and 5-nitro-2-thiophene semicarbazone (4) were synthesized and crystallized. The three new crystal structures of 1, 2, and 4 were determined and compared to three already known crystal structures of 3. Additionally, two new polymorphic forms of
四种化合物,即:5-硝基-2-糠醛缩氨基硫脲(1);5-硝基-2-噻吩缩氨基硫脲 (2);5-硝基-2-糠醛缩氨基脲(3);合成并结晶了 5-硝基-2-噻吩缩氨基脲 (4)。确定了 1、2 和 4 的三种新晶体结构,并将其与三种已知的 3 晶体结构进行了比较。此外,合成并研究了 1 溶剂化物的两种新多晶型。2-噻吩与2-糠醛的交换以及缩氨基硫脲和缩氨基脲的交换对超分子网自组装的影响从形成的合成子和组装的角度进行了阐明和讨论,并伴随着完整的相互作用图分析。
