A three-dimensional cadmium(II) coordination polymer: poly[[[μ-4,4′-(propane-1,3-diyl)dipyridine-κ2N:N](μ-3,3′-thiodipropionato-κ3O,O′:O)cadmium(II)] monohydrate]

Abstract

In the title coordination polymer, {[Cd(C6H8O4S)(C13H14N2)]·H2O}n, the CdIIatom displays a distorted octahedral coordination, formed by three carboxylate O atoms and one S atom from three different 3,3′-thiodipropionate ligands, and two N atoms from two different 4,4′-(propane-1,3-diyl)dipyridine ligands. The CdIIcentres are bridged through carboxylate O atoms of 3,3′-thiodipropionate ligands and through N atoms of 4,4′-(propane-1,3-diyl)dipyridine ligands to form two different one-dimensional chains, which intersect to form a two-dimensional layer. These two-dimensional layers are linked by S atoms of 3,3′-thiodipropionate ligands from adjacent layers to form a three-dimensional network.
