The assembly of coordination polymers from metal ions and organic moieties is currently attracting considerable attention in crystal engineering due to their intriguing architectures and potential applications as functional materials. A new coordination polymer, namely poly[[μ2‐trans‐1,2‐bis(pyridin‐3‐yl)ethylene‐κ2N:N′]bis(μ4‐4,4′‐oxydibenzoato‐κ6O:O,O′:O′′:O′′,O′′′)dicadmium(II)], [Cd2(C14H8O5)2(C12H10N2)]n
由金属离子和有机部分组成的配位聚合物的组装,由于其引人入胜的结构和作为功能材料的潜在应用,目前在晶体工程中引起了相当大的关注。一种新的配位聚合物,即聚[[μ 2 -反式-1,2-双(吡啶-3-基)乙烯- κ 2 Ñ:Ñ ']双(μ 4 -4,4'- oxydibenzoato-κ 6 ö:O,O ′:O ′′:O ′′,O ′′′)二镉(II)],[Cd 2(C 14 H 8 O 5)2(C通过Cd(NO 3)2 ·4H的自组装合成了12 H 10 N 2)] n或[Cd 2(4,4'-OBB)2(3,3'-BPE)] n在水热条件下2 O,4,4'-氧二苯甲酸(4,4'-H 2 OBB)和反式1,2-双(吡啶-3-基)乙烯(3,3'-BPE)。通过红外光谱,元素分析和单晶X射线衍射分析对标题化合物进行结构表征。每个Cd II中心由来自四个不同4,4'-OBB 2-的六个羧酸O原子配位配体和一个吡啶基N原子形成3
