在水热条件下,利用4,4′-联吡啶硫与高氯酸银反应合成了一种新型配合物{[Ag(dps)ClO4].H2O}n(其中4-dps=4,4′-联吡啶硫),借用元素分析和X-射线单晶衍射仪对其进行了表征。结果表明,配合物属单斜晶系,空间群C2/c;晶胞参数:a=1.3 602(2)nm,b=0.99 188(16)nm;c=2.0 516(3)nm,β=102.385(2)°;V=2 703.5(7)A3;Z=8;最终偏离因子R=0.0 730,ωR=0.1 222。配合物中银原子通过4,4′-联吡啶硫的N原子的直线配位方式的连接,沿a轴方向形成一维聚合链。毗邻的一维链籍氢键和π-π堆积相互作用拓展为三维超分子结构。
A new complex {[Ag (dps) ClO4] .H2O} n (where 4-dps = 4,4 ’ - Bipyridyl Sulfur), which was characterized by elemental analysis and X-ray single crystal diffractometry. The results show that the complex belongs to the monoclinic system with space group C2 / c. The unit cell parameters are a = 1.3602 (2) nm, b = 0.99188 (16) nm and c = 2.0516 102.385 (2) °; V = 2 703.5 (7) A3; Z = 8; final deviation factor R = 0.0 730, ωR = 0.1 222. The silver atoms in the complex are connected by the linear coordination of the N atoms of 4,4’-dipyridylthiol to form one-dimensional polymer chains along the a-axis. The adjacent one-dimensional chain hydrogen bonds and π-π stacking interactions develop into three-dimensional supramolecular structures.
