Abstract: The title complex, [Nd2(C8H3NO6)2(C8H4NO6)2(H2O)6]·2H2O, consists of dimeric units related by an inversion center. The NdIII atom is nine-coordinated by three O atoms from water molecules and six from carboxylate atoms. The 1,2-dicarboxylate acid molecules are in a single and double deprotonation stage and exhibit two coordination modes, viz. 2-(4, O1: O2: O2: O3) and 1-(2, O2: O3), which are responsible for the dimeric structure framework. The dimeric structure is then assembled into a three-dimensional supramolecular framework via O-HO hydrogen bonds.
