ligands bis(3-pyridyl)methylvinylsilane (L1) and 1,2-di(3-quinolyl)dimethyl disilane (L2). The complexation reactions of both these ligands with Ag(I), Pd(II) and Cu(II) have been explored. The 1H, 13C1H} and 29Si1H}NMR and IR spectra of both the ligands and their metal complexes have been found characteristic. The complex of L1 with silver(I), [Ag(L1)]ClO4 (1) gives suitable single crystals characterized
3-溴吡啶和3-溴喹啉与正丁基锂反应生成锂化产物,其在-78°C下与二氯甲基乙烯基硅烷和1,2-二氯二甲基二硅烷反应生成配体双(3-吡啶基)甲基乙烯基硅烷(L1)和1,2 -二(3-喹啉基)二甲基乙硅烷(L2)。已经探索了这两种配体与Ag(I),Pd(II)和Cu(II)的络合反应。已发现配体及其金属配合物的1 H,13 C 1 H}和29 Si 1 H} NMR和IR光谱是特征性的。复杂的L1与银(I)和[Ag(L1)] CLO 4(1)给出以X射线衍射为特征的合适的单晶。其结构由二维片材,具有25元metallamacrocycle环,其中的Ag具有扭曲的四面体的几何形状和被结合到乙烯基(η 2)基团。发现AgCF 3 SO 3与L1反应并使所得络合物的单晶进行X射线衍射后,发现与1相反,乙烯基和银之间没有键,从而产生了无限的分子链,其中配位几何结构的银是扭曲的三角形平面。碳纤
