摘要: 通过溶剂挥发法,由4,4'-联吡啶(4,4'-bpy),2,4,6-三巯基均三嗪(ttcH3)及含有不同反位阴离子的Mn盐制备了配位聚合物{[Mn(ttcH2)2(bpy)]·bpy}n。X-射线单晶衍射结构分析表明该配位聚合物结晶于单斜晶系,C2/c空间群。中心Mn离子的畸变八面体配位几何由一对处于硫酮异构型式的ttcH2-阴离子的两对N和S原子以及两个4,4'-bpy配体的两个N原子构成。而4,4'-bpy配体则通过两个吡啶环上的N原子将相邻的金属Mn离子桥接为一维(1D)链状结构。该1D链状配位聚合物通过链间的氢键作用及与晶格中游离4,4'-bpy的氢键作用进一步拓展为三维(3D)超分子网络结构。

Abstract: Self-assembly of 4,4'-bipyridine (4,4'-bpy) and trithiocyanuric acid (ttcH3) with Mn(OAc)2·4H2O affords a new coordination polymer {[Mn(ttcH2)2(bpy)]·bpy}n. Single-crystal X-ray analysis indicates that complex crystallizes in monoclinic crystal system, C2/c space group. The Mn atom is coordinated by two pairs of S and N atoms from two ttcH2-anions, and two N atoms from two 4,4'-bpy ligands. The adjacent Mn(Ⅱ) centers are extended to afford a one-dimensional (1D) polymeric chain via the bridging of bpy ligands. These 1D chains are connected to a three-dimensional (3D) supramolecular network via various hydrogen bonds.

Key words: Mn coordination complex, trithiocyanuric acid, 4,4'-bipyridine, coordination polymer, crystal structure
