Abstract:
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 coordinating water molecule and the remaining ones from the 3-(3-hy-droxy-phen-yl)prop-2-enoatate anions (one bidentate, two bidentate and bridging, two monodentate bridging), leading to a distorted tricapped trigonal-prismatic coordination polyhedron surrounded by solvent water mol-ecules. In the crystal, extensive intermolecular O-H⋯O hydrogen-bonding inter-actions and π-π inter-actions [centroid-centroid separation = 3.9393 (1) Å] lead to the formation of a three-dimensional supra-molecular network.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
