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
