Abstract

The title compound, {[Nd(2)(CH(2)CHCOO)(6)(H(2)O)(3)]·3H(2)O}(n), was synthesized by hydro-thermal methods. The structure contains one-dimensional coordination polymers in which two distinct Nd(III) atoms show different coordination modes. One is coordinated by four bidentate acrylate ligands, two of which bridge Nd(III) atoms, and by two O atoms from a further two bridging acrylate ligands. The other Nd(III) atom is coordinated by two bidentate acrylate ligands, two O atoms from bridging acrylate ligands, and three water mol-ecules. Extensive hydrogen bonding between the coordinated and uncoordin-ated water mol-ecules and the O atoms of the acrylate ligands link the coordination polymers into a three-dimensional network.
