Abstract

The title compound, {[Nd2(CH2CHCOO)6(H2O)3]·3H2O}n, was synthesized by hydrothermal methods. The structure contains one-dimensional coordination polymers in which two distinct NdIII atoms show different coordination modes. One is coordinated by four bidentate acrylate ligands, two of which bridge NdIII atoms, and by two O atoms from a further two bridging acrylate ligands. The other NdIII atom is coordinated by two bidentate acrylate ligands, two O atoms from bridging acrylate ligands, and three water molecules. Extensive hydrogen bonding between the coordinated and uncoordinated water molecules and the O atoms of the acrylate ligands link the coordination polymers into a three-dimensional network.
