1-D链配位聚合物Cu(C5H5N)2Cl2n通过氯离子(μ-Cl-)桥连构建

摘要

在标题配位聚合物[Cu(C5H5N)2Cl2]n中,每个铜离子与4个氯离子和2个吡啶氯原子配位,形成[4+2]拉长的八面体几何构型.其中2个铜离子通过μ-Cl-桥连中心对称的二聚体,同时二聚体再通过μ-Cl-桥连,得到1-D链沿着a-铀方向延伸,这种无限1-D链进一步通过氢键C-H…Cl相连,在(001)平面内得到2-D网状的超分子.%In the title complex, [Cu(C5H5N)2Cl2]n, the coordination sphere around each Cu atom can be described as a [4+2] tetragonally elongated octahedron comprised of four Cl- ions and two N atoms from two pyridines. Two inversion-related Cu2+ ins are bridged by bis μ-chloro ligands, forming a centrosymmetric dimeric unit, interdimeric contacts leading to a chainlike arrangement which run parallel to the a-axis direction. The infinite chains are further linked by C-H…Cl hydrogen bonds to give rise to a (001) sheet.
