Abstract: In the title compound, [Er2(C4H4O4)3(H2O)2]n, the asymmetric unit consists of two ErIII cations, three succinate anions and two coordinated water molecules. Both ErIII ions are in a tricapped trigonal-prismatic coordination environment. The Er atoms are bridged into a three-dimensional framework by succinate anions, which exhibit anti and gauche conformations with different coordination modes. The crystal structure is stabilized by O-HO hydrogen bonds [OO = 2.715 (8)-2.936 (8) Å].
