| Abstract: | A new three-dimensional open-framework cobalt(II)-tungsten(VI) phosphate, [H3NCH2CH2NH3]3?[Co3W4P4O28](1) has been synthesized from the reaction of CoCl2?6H2O, WO3, H3PO4, ethylenediamine and H2O. The title compound was fully characterized by infrared spectroscopy, elemental analysis, magnetic properties, thermogravimetric analysis, XPS and single-crystal X-ray diffraction. The compound crystallized in a tetragonal space group I4(1)/a with a=1.7118(4) nm, c=1.0773(2) nm, V =3.1568(11) nm3, Z =4. |
