本文合成了10种新型的含吡嗪衍生物的银磺酸盐[Ag（L1）（Pyr）（H2O）]（1），[Ag（L1）（2，3-Pyr）]（2），[Ag（L1）（2，5-Pyr）] xH 2 O（3），[Ag（L1）（2，5-Pyr）] xH 2 O（4），[Ag（L1）（2，5-Pyr）] xH 2 O（5），[Ag（L1）（2，5-Pyr）] xH 2 O（5），[Ag（L1）（2，5-Pyr）] xH 2 O（6），[Ag（L1）（2，5-Pyr）] xH 2 O（6），[Ag（L1）（2，5-Pyr）] xH 2 O（7），[Ag（L1）（2，5-Pyr）] xH 2 O（7（2，3，5-Pyr）]（4）、[Ag（L1）（2，3，5，6-Pyr）]（5）、[Ag（L2）（Pyr）]（6）、[Ag（L2）（2，3-Pyr）]（7）、[Ag（L2）（2，6-Pyr）]（8）、[Ag（L2）（2-Pyr）]（9）和[Ag（L2）（2，5-Pyr）] x H2O（10）（L1 = 3-氨基-4-甲基苯磺酸根阴离子; L2 = 2-氨基-3，5-二甲基苯磺酸根阴离子; Pyr =吡嗪; 2-Pyr = 2-甲基吡嗪; 2，3-Pyr = 2，3-二甲基吡嗪; 2，6-Pyr = 2，6-二甲基吡嗪; 2，5-Pyr = 2，5-二甲基吡嗪; 2，3，5-Pyr = 2，3，5-三甲基吡嗪; 2，3，5，6-Pyr = 2，3，5，6-四甲基吡嗪），并通过元素分析、红外光谱和X射线晶体学进行了表征。在1和7中，银（I）中心通过桥连吡嗪配体连接以形成一维（1D）链。化合物2-6的银（I）离子通过吡嗪配体和磺酸根阴离子桥接形成二维聚合物结构。化合物8-10显示具有金刚石拓扑结构的3D结构。这些结果表明吡嗪衍生物的空间位阻和含不同取代基的磺酸根阴离子在银（I）聚合物骨架形成中起重要作用。此外，还对这些化合物的发光性质进行了详细的讨论。
In this paper, ten novel silver(I) sulfonates containing pyrazine derivatives, [Ag(L1)(Pyr)(H2O)] (1), [Ag(L1)(2,3-Pyr)] (2), [Ag(L1)(2,5-Pyr)] x H2O (3), [Ag(L1)(2,3,5-Pyr)] (4), [Ag(L1)(2,3,5,6-Pyr)] (5), [Ag(L2)(Pyr)] (6), [Ag(L2)(2,3-Pyr)] (7), [Ag(L2)(2,6-Pyr)] (8), [Ag(L2)(2-Pyr)] (9), and [Ag(L2)(2,5-Pyr)] x H2O (10) (L1 = 3-amino-4-methylbenzenesulfonate anion; L2 = 2-amino-3,5-dimethylbenzenesulfonate anion; Pyr = pyrazine; 2-Pyr = 2-methylpyrazine; 2,3-Pyr = 2,3-dimethylpyrazine; 2,6-Pyr = 2,6-dimethylpyrazine; 2,5-Pyr = 2,5-dimethylpyrazine; 2,3,5-Pyr = 2,3,5-trimethylpyrazine; 2,3,5,6-Pyr = 2,3,5,6-tetramethylpyrazine), have been synthesized and characterized by elemental analyses, IR spectroscopy and X-ray crystallography. In 1 and 7, the silver(I) centers are linked by bridging pyrazine ligands to form one-dimensional (1D) chains. The silver(I) ions of the compounds 2-6 are bridged by pyrazine ligands and sulfonate anions to form 2D polymeric structures. Compounds 8-10 show 3D structures with diamond topologies. These results indicate that the steric hindrance of the pyrazine derivatives and the sulfonate anions containing different substituting groups play important roles in the framework formation of the silver(I) polymers. In addition, the luminescent properties of these compounds are also discussed in detail.
