Abstract

The title compound, [Nd(C8H6NO4)(C2O4)(H2O)]n, is a layer-like coordination polymer. The NdIII ion is coordinated by four carboxylate O atoms from three bridging 5-azaniumylisophthalate (Haip) ligands, four carboxylate O atoms from two oxalate (ox) anions and one ligated water molecule in a tricapped trigonal–prismatic geometry. The Haip anion acts as a μ3-bridge, connecting three NdIII ions through two carboxylate groups; the ox anion adopts a bis-bidentate-bridging mode, linking two NdIII ions. The layer framework is further extended to a three-dimensional supramolecular structure through N—H⋯O and O—H⋯O hydrogen bonds.
