In the title compound, [Gd(C(8)H(6)NO(2))(3)(H(2)O)](n), the gadolinium(III) ion is coordinated by eight carboxyl-ate O atoms and one water mol-ecule. The carboxyl-ate ligands bridge pairs of gadolinium(III) ions, forming a zigzag chain along [100]. Hydrogen bonds link the chains into sheets parallel to (001).

The title Sm(III) compound, {[Sm(C(9)H(7)O(3))(3)(H(2)O)]·H(2)O}(n), was obtained under hydrothermal conditions. Its structure is isotypic with the analogous Eu complex. The latter was reported incorrectly in space group P1 by Yan et al. [J. Mol. Struct. (2008), 891, 298-304]. This was corrected by Marsh [Acta Cryst. B65, 782-783] to P-1. The Sm(III) ion is nine-coordinated by O atoms from one ...
