Coordination polymers of zinc with 2,2'-(2,3-bis-phenylsulfanylnaphthalene-1,4-yloxy)diacetate with different ancillary ligands such as pyridine, dimethylformamide and water are prepared and characterized. The dimensionality of zinc derived coordination polymers from (4-carboxymethoxy-2, 3-bis-phenylsulfanyl naphthalene-1-yloxy)-diacetate can be changed by ancillary ligands. In the case of pyridine as ancillary ligand it forms a one-dimensional coordination polymer, whereas in the case of dimethylformamide it is a two-dimensional polymer.
