Two new inorganic–organic coordination polymers, namely poly[[μ6-2-(4-1-[4-(carboxymethoxy)phenyl]-1-methylethyl}phenoxy)acetato][μ4-2-(4-1-[4-(carboxymethoxy)phenyl]-1-methylethyl}phenoxy)acetato]disodium(I)], [Na2(C19H19O6)2]n, (I), and poly[hexa-μ-aqua-diaquabisμ3-2,2′-[sulfonylbis(1,4-phenyleneoxy)]diacetato}tetrasodium(I)], [Na4(C16H14O8)2(H2O)8]n, (II), have been prepared. In (I), the asymmetric unit contains two NaIcations and two 2-(4-1-[4-(carboxymethoxy)phenyl]-1-methylethyl}phenoxy)acetate (HL1−) ligands. Each NaIcation is octahedrally coordinated by two ether O atoms and four carboxylate O atoms of three different HL1−ligands. The NaO6polyhedra share edges to form an inorganic ribbon along theaaxis. These inorganic ribbons are further connected by the HL1−ligands to generate two-dimensional layers parallel to the (001) plane. The structure of (II) consists of ribbons of four crystallographically independent Na atoms (three six- and one five-coordinate), which are bridged by carboxylate O atoms of 4,4′-[sulfonylbis(1,4-phenyleneoxy)]diacetate (L22−) ligands and water molecules. These ribbons are interlinked byL22−ligands through two different coordination modes to afford a three-dimensional network.
