Catena-Poly[[[aqua-[3-(3-hy-droxy-phen-yl)prop-2-enoato]samarium(III)]-bis-[?(2)-3-(3-hy-droxy-phen-yl)prop-2-enoato]] monohydrate].

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 ?-? inter-actions [centroid-centroid separation = 3.9393?(1)?Å] lead to the formation of a three-dimensional supra-molecular network.
