Description
Summary:The title compound, [La2(C8H3NO6)2(C8H4NO6)2(H2O)6][dot]2H2O, consists of dimeric units related by an inversion center. The two LaIII atoms are linked by two bridging bidentate carboxylate groups and two monodentate carboxylate groups. Each LaIII atom is nine-coordinated by six O atoms from five different carboxylate groups and three from water molecules. Hydrogen bonds between the water molecules and between the solvent water and a carboxylate O atom are observed in the structure. In the crystal packing, there are slipped pi-pi stacking interactions between the parallel benzene rings. Both hydrogen-bonding and pi-pi interactions combine to stabilize the three-dimensional supra-molecular network.[PUBLICATION ABSTRACT]
