Abstract
The title compound, Sm-2(C3H2O4)(3)(H2O)(6)](,) was investigated by X-ray diffraction. It crystallizes in the monoclinic space group C2/c with cell parameters a = 17.1650(8) , b = 12.3010(5) , c = 11.1420(4) , beta = 127.5161(10)A degrees, Z = 4 and V = 1866.04(14) (3). The Sm atom lies on a two-fold axis and has nine-coordination with six oxygen atoms from carboxylate groups and three water molecules. The compound forms a layer-type polymeric structure. The layers are formed by samarium and one independent malonate group to give a three-dimensional framework. The extensive network of hydrogen bonds and bridge bonds observed in this structure enhances the structural stability. The thermal dehydration of the compound was investigated by thermogravimetric analysis.
