"郭倩玲, 屈轶欣(北京化工大学化学工程学院, 北京100029);舒兰(北京师范大学化学系, 北京100875)。基于钠离子和水溶性p-磺酸噻卡环[4]芳烃的二维配位聚合物[Na(H2O)2Y(H2O)6(DMF)(p-磺酸噻卡环[4]芳烃)]·9H2O的合成与结构"
这篇论文报道了一种由钠离子和水溶性p-磺酸噻卡环[4]芳烃构建的二维配位聚合物——[Na(H2O)2Y(H2O)6(DMF)(p-磺酸噻卡环[4]芳烃)]·9H2O，该复合物属于单斜晶系，空间群为P21/c。其晶体结构参数为a=16.703(3)Å, b=17.819(4)Å, c=17.357(4)Å, α=106.23(3)°, Z=4, V=4960.0(17)ų, Mr=1304.08, Dc=1.746g/cm³, μ=1.624mm⁻¹。通过X射线单晶衍射分析，得到了7534个观测反射，其中1>2σ(1)的反射数据用于结构解析，最终R值为0.0398，wR值为0.1132。
在这个配位聚合物中，一个三价钇离子通过硫醇基团与噻卡环[4]芳烃配体连接，同时，DMF分子的一个氧原子占据噻卡环[4]芳烃的空腔进行配位，并且还有六个水分子作为配体与钇离子相连。这种配位方式形成了一个稳定的二维网络结构。p-磺酸噻卡环[4]芳烃在这里起到了桥梁作用，通过其磺酸基团与金属离子形成强配位键，增强了结构的稳定性。
此外，这种配位聚合物的研究不仅在配位化学领域具有重要意义，还可能对材料科学、催化和分子识别等领域产生影响。它展示了金属离子如何与有机配体结合形成复杂结构的可能性，为设计新型功能材料提供了新的思路。同时，由于p-磺酸噻卡环[4]芳烃的水溶性特性，这种复合物可能在水处理或环境科学中有潜在的应用价值。

various intrinsic characteristics. With larger elec-
tron-rich cavity than CAS, TCAS shows much dif-
ferent inclusion behavior towards some organic
molecules and metal ions in solution and solid-
state"0-141.
Moreover, TCAS can bind metal ions not
only at the upper and lower rims but also at the
linker positions, which makes it a good candidate for
constructing polymers. As reported, it tends to form
tetranuclear bivalent anions with transition-metal
ions and further extend its structure through metal-
sulfonate oxygen bonds into a 2D
layerI15-171.
