A three-dimensional cadmium(II) coordination polymer: poly[[[[mu]-4,4'-(propane-1,3-diyl)di­pyridine-[kappa]²N:N]([mu]-3,3'-thio­dipropionato-[kappa]³O,O':O)cadmium(II)] mono­hydrate]

In a Cd^II coordination polymer formed by 3,3'-thio­dipropionate and 4,4'-(propane-1,3-diyl)di­pyridine ligands, the Cd^II centres are bridged through carboxyl­ate O atoms and pyridine N atoms to form two different one-dimensional chains which intersect to form a two-dimensional layer. These two-dimensional layers are linked by S atoms to form a three-dimensional network.

The two-dimensional coordination polymer poly[di­aqua­(μ₂-1H-imid­azo[4,5-f][1,10]phenanthroline)-μ₄-sulfato-μ₃-sulfato-dicadmium(II)]

In the Cd^II coordination polymer formed by 1H-imidazo[4,5-f][1,10]phenanthroline (IP), sulfate and water ligands, there are two crystallographically independent Cd^II centres with different coordination geometries. The Cd^II ions are alternately bridged by O atoms from two sulfate ligands, forming one-dimensional chains, which are bridged by the IP ligands to form two-dimensional layers. These layers are linked by inter­molecular hydrogen bonds, leading to the formation of a three-dimensional supra­molecular network.
