Two new coordination compounds, [Cu(L)2SO4]·0.5H2O·0.5CH2Cl2 (1) and [Cu(L)2(SCN)2]·3CHCl3 (2), were synthesized and structurally characterized. The molecular architectures of the 4,4â²-di(3-methyl)pyridyl sulfide (L) coordination polymer networks are anion dependent. The molecular architecture of 1 is a 3-D non-interpenetrating network, SO42â serving as a bridging ligand to connect two copper ions resulting in a rhombic box with a volume of 793 Ã
3. While 2 is a 2-D planar network with SCNâ acting as a mono-coordinating ligand. Guest adsorption experiments show that 1 prefers to selectively adsorb 4-chlorophenol rather than nitrobenzene and benzophenone and DMF. In contrast, 2 does not adsorb any of the above guest species.
我们合成了[Cu(L)2SO4]Â-0.5H2OÂ-0.5CH2Cl2(1)和[Cu(L)2(SCN)2]Â-3CHCl3(2)这两种新的配位化合物,并对其进行了结构表征。4,4â²-二(3-甲基)

吡啶(L)配位聚合物网络的分子结构与阴离子有关。1 的分子结构为三维非穿透网络,SO42â 作为桥接
配体连接两个
铜离子,形成一个体积为 793 Ã 3 的菱形盒。而 2 是一种二维平面网络,SCNâ 是一种单配位
