外文摘要：In the title coordination polymer, [Cd-2(SO4)(2)(C13H8N4)-(H2O)(2)](n), there are two crystallographically independent Cd-II centres with different coordination geometries. The first Cd-II centre is hexacoordinated by four O atoms of four sulfate ligands, one water O atom and one N atom of a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, giving a distorted octahedral coordination environment. The second Cd-II 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 antitrigonal prismatic geometry. The symmetry-independent Cd-II 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 interlayer hydrogen bonds, leading to the formation of a three-dimensional supramolecular network.
