Hydrothermal synthesis, crystal structures and characterizations of a novel 3D metal phosphonate:: Mg0.5Cd[O3PCH(OH)CO2]

A novel cadmium and magnesium phosphonate compound Mg0.5Cd[O3PCH(OH)CO2] (1) has been synthesized by hydrothermal reaction at 110 degrees C and characterized by single-crystal X-ray diffraction as well as with infrared spectroscopy, elemental analysis and thermogravimetric analysis. The structure of 1 comprises CdO6 octahedra and MgO6 octahedra connected by [O3PCH(OH)CO2](3-) to form 3D framework with one-dimensional channel system in the a-axis direction. (C) 2006 Elsevier B.V.
