2-isonicotinato-2-oxalato-terbium(III)]Abstract: In the crystal structure of the title complex, [Tb(C6H4NO2)(C2O4)(H2O)2]n, the TbIII cation is coordinated by four O atoms from two oxalate ligands, two O atoms from two isonicotinate ligands and two O atoms from water molecules within a distorted square-antiprismatic coordination. The TbIII cation, the isonicotinate anion and the two crystallographically independent water molecules occupy general positions, whereas one of the two crystallographically independent oxalate anions is located on a center of inversion, and the second oxalate anion is located on a twofold rotation axis. The TbIII cations are linked by the oxalate and isonicotinate anions into layers, which are connected via intermolecular hydrogen-bonding and ![[pi]](/logos/entities/pi_rmgif.gif)
