Abstract

The malonate complex of Nd2mal3.6H2O was prepared and its crystal structure determined by X-ray diffraction method. It crystallises in the monoclinic space group C2c with cell parameters a=17.2240(1) Å, b=12.3690(7) Å, c=11.2070(7) Å, β=127.532(4)° Z=4 and V=1893.4(2) Å3. The compound forms a layer-type polymeric structure. The layers are formed by neodymium and one independent malonate group, giving a three-dimensional framework structure. 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 TGA measurements. The structure model is consistent with the vibrational behavior and the three different temperatures observed in the dehydration process.
