Abstract: The structure of the title compound, [C(NH2)3]2[Nd2(C6H5O7)2(C2O4)(H2O)2]·7H2O, contains anionic layers in which every Nd atom is linked to three other Nd atoms by citrate anions and to one Nd atom by the centrosymmetric oxalate anion. The Nd atoms are ten-coordinated; their coordination polyhedra form pairs sharing one edge owing to bridging by O atoms of carboxylate groups of citrate anions.
