spectroscopy. Molecular structures of (2-C4H3S)3Sb (1); (2-C4H3S)3SbBr2 (4) and Ag[(2-C4H3S)3Sb]2}NO3 (6) were determined by X-ray spectroscopy. This is the first X-ray crystallographic report on stibines containing heterocyclic aromatic groups and their silver complexes. The stibine (1) is pyramidal while its dibromide has trigonal bipyramidal structure. The silver complex (6) has a polymeric nature with NO3−
该工作提出了具有通式(2-C 4 H 3 X)3 Sb的杂环芳族基的叔stibines的合成,其中X = S(1),O(2)或NMe(3)。将这些stibines溴化,得到相应的二溴化物,并与硝酸银(I)络合。通过元素分析,IR,UV,质量,1 H,13 C,COSY,HETCOR NMR光谱对特征蛋白,二溴化物及其银络合物进行表征。(2-C 4 H 3 S)3 Sb(1)的分子结构;(2-C 4 H 3 S)3通过X射线光谱法测定了SbBr 2(4)和Ag [(2-C 4 H 3 S)3 Sb] 2 } NO 3(6)。这是关于含有杂环芳族基团及其银配合物的stibines的第一个X射线晶体学报告。st啶(1)是金字塔形的,而其二溴化物具有三角双锥体结构。银络合物(6)具有一个NO聚合物性质3 -充当桥连配体。
