外文摘要：In the title coordination polymer, [Cd2(SO4)2(C13H8N4)(H2O)2] n , there are two crystallographically independent CdII centres with different coordination geometries. The first CdII centre is hexacoordinated by four O atoms of four sulfate ligands, one water O atom and one N atom of a 1H-imid-azo[4,5-f][1,10]phenanthroline (IP) ligand, giving a distorted octa-hedral coordination environment. The second CdII centre is heptacoordinated by four O atoms of three sulfate ligands, one water O atom and two N atoms of one chelating IP ligand, resulting in a distorted monocapped anti-trigonal prismatic geometry. The symmetry-independent CdII ions are bridged in an alternating fashion by sulfate ligands, forming one-dimensional ladder-like chains which are connected through the IP ligands to form two-dimensional layers. These two-dimensional layers are linked by inter-layer hydrogen bonds, leading to the formation of a three-dimensional supra-molecular network. ? 2014.
