| Abstract: | Two modifications of hexaaquamagnesium(II) hypophosphite Mg(H2O)6](H2PO2)2 have been synthesized and structurally characterized. Literature data are available for one of these forms. The geometrical characteristics of hexaaqua cations, hypophosphite anions, and nets of hydrogen bonds between the hypophosphite anions and the coordinated water molecules are analyzed. The packing motif of the structure-forming fragments was found to be the same for the two structures, except that modification of the inner structure of the complex cation leads to different nets of hydrogen-bonded cations and anions. |
