Poly[diaquabis(2,2′-bipyridine)tris(μ4-2,2′-bipyridine-4,4′-dicarboxylato)dineodymium(III)]
Abstract
In the crystal structure of the title mixed-ligand coordination polymer, [Nd2(C12H6N2O4)3(C10H8N2)2(H2O)2]n, the NdIII 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 NdIII ion is a bicapped trigonal prism. Two NdIII centers are bridged by four carboxylate groups to form an Nd2 dimeric unit; these are further connected by 2,2′-bipyridine-4,4′-dicarboxylate linkers, resulting in a layered coordination network.
