to form normal coordination bonds, while the sulfur atoms only show weak interactions with silver atoms and the intermolecular AgS weak contacts connect the low-dimensional complexes into high-dimensional supramolecular networks. Additional weak interactions, such as pi-pi stacking, F...F weak interactions, Ag...O contacts or C-H...O hydrogen bonds, also help to stabilize the crystal structures. It was
四个灵活的四齿配体,1,3-双(2-吡啶硫基)丙烷(L1),1,4-双(2-吡啶硫基)丁烷(L2),1,5-双(2-吡啶硫基)戊烷( L3)和1,6-双(2-吡啶硫基)己烷(L4)与AgX(X = BF4-,ClO4-,PF6-或CF3SO3-)导致形成七个新的配合物:[AgL1(BF4)] 2(1),[[AgL2](ClO4)]无穷大(2),[[AgL2(CH3CN)](PF6)]无穷大(3),[[AgL3](BF4)(CHCl3)] 2(4), [[AgL3(CF3SO3)](CH3OH)(0.5)]无穷大(5),[[Ag2L4(2)](BF4)2]无穷大(6)和[[AgL4](PF6)]无穷大(7),通过元素分析,红外光谱和X射线晶体学对其进行了表征。单晶X射线分析表明,配合物1和4具有双核大金属环结构,而配合物2、3和5-7具有链结构。在所有的综合体中 配体的氮原子优先与银原子配位
