Two new two-dimensional coordination polymers, poly[[[aqua(2,2'-bipyridine-kappa2N,N')manganese(II)]-mu3-p-phenylenebis(oxyacetato)-kappa3O:O':O''] dihydrate], {[Mn(C10H8O6)(C10H8N2)(H2O)].2H2O}n, (I), and poly[[di-mu-aqua-bis[aquasodium(I)]]-mu4-p-phenylenebis(oxyacetato)-kappaO:O',O'':O''',O'''':O'''''], [Na2(C10H8O6)(H2O)4]n, (II), have been synthesized and characterized by X-ray single-crystal diffraction. In (I), there are two 1,4-BDOA2- [p-phenylenebis(oxyacetate) or, more commonly, benzene-1,4-dioxyacetate] ligands, each lying about inversion centres, while in (II), there is one such ligand and it also has crystallographically imposed inversion symmetry. In (I), each Mn(II) atom displays an octahedral MnN2O4 configuration, defined by three carboxyl O atoms of different 1,4-BDOA2- groups, two N atoms of one 2,2'-bipyridine ligand and one water molecule. In (II), each Na(I) atom is octahedrally coordinated by one ether O atom, two carboxyl O atoms of different 1,4-BDOA2- ligands and three water molecules. The metal ions in complexes (I) and (II) are bridged by 1,4-BDOA2- groups into two-dimensional layer structures. Furthermore, three-dimensional supramolecular networks are constructed via hydrogen bonds in (I) and (II), and by additional pi-pi stacking interactions in (I).
