Abstract Two new silver(I) complexes 2-diphenylphosphinopyridine (dppy), {Ag2(dppy)2[N(CN)2]}2[μ-N(CN)2]2 (1) and {Ag2(dppy)2[μ-C(CN)3]2}n (2) linked by dicyanamide (N(CN)2−) or tricyanomethanide (C(CN)3−) were synthesized and characterized by X-ray crystallography. Complex 1 forms a tetranuclear structure with two binucleate moieties [Ag2(dppy)2]+ linked by two dicyanamide ligands. Interestingly, when bridging ligand is changed to tricyanomethanide, complex 2 displays one-dimensional infinite chain structure. Both complexes exhibit strong blue emission with phosphorescent quantum yields of 13.4% for 1 and 39.2% for 2 in solid state.

由2-二苯基膦吡啶和双氰胺或三氰基甲烷构建的蓝色发光银(I)配合物

摘要 两种新的银 (I) 配合物 2-二苯基膦吡啶 (dppy), {Ag2(dppy)2[N(CN)2]}2[μ-N(CN)2]2 (1) 和 {Ag2(dppy)2 [μ-C(CN)3]2}n (2) 由双氰胺 (N(CN)2-) 或三氰基甲烷 (C(CN)3-) 连接，合成并通过 X 射线晶体学表征。复合物 1 形成一个四核结构，其中两个双核部分 [Ag2(dppy)2]+ 由两个双氰胺配体连接。有趣的是，当桥接配体变为三氰基甲烷时，配合物 2 显示出一维无限链结构。两种配合物都表现出强烈的蓝色发射，固态下的磷光量子产率为 1 的 13.4% 和 2 的 39.2%。
