new thiadiazole ligand, N-ethyl-5- (benzo[b]thien-2-yl-)-1,3,4-thiadiazol-2-amine (BTH), was prepared from 3-methyl-1-benzofuran-2-carboxylic acid and N-ethylhydrazinecarbothioamide precursors. Corresponding silver(I) complex, tetrakis(N-ethyl-5-(benzo[b]thien-2-yl-)-1,3,4-thiadiazol-2-amine)silver(I) nitrate [Ag2(BTH)4](NO3)2 (1), was prepared. The structures of BTH and 1 were characterized by 1H-NMR
摘要 以 3-甲基-1-苯并呋喃为原料制备了新型噻二唑配体 N-乙基-5-(苯并[b]噻吩-2-基-)-1,3,4-噻二唑-2-胺 (BTH)。 -2-羧酸和N-乙基肼碳硫酰胺前体。对应的银(I)络合物,四(N-乙基-5-(苯并[b]噻吩-2-基-)-1,3,4-噻二唑-2-胺)银(I)硝酸[Ag2(BTH) 4](NO3)2 (1),制备。BTH和1的结构通过1H-NMR、13C-NMR、FT-IR、元素分析和HR-MS技术表征。此外,1 的分子结构被 X 射线晶体学照亮。由于强烈的anagsotic相互作用,即使在2:1金属配体化学计量中具有两个相同的配体,复合物的晶体结构也显示出一个有趣的不对称单体单元。通过固体和溶液介质发射测量研究了配合物的光致发光特性。
