Poly[diaqua­bis(2,2′-bipyridine)tris­(μ(4)-2,2′-bipyridine-4,4′-dicarboxyl­ato)dineodymium(III)]

In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa­hedral coordination environment formed by one water mol­ecule, one chelating 2,2′-bipyridine ligand, and five monodentate carboxyl­ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Two Nd(III) centers are bridged by four carboxyl­ate groups to form an Nd(2) dimeric unit; these are further connected by 2,2′-bipyridine-4,4′-dicarboxyl­ate linkers, resulting in a layered coordination network.
