Abstract
[2,6-(CH3)2C6H3NH3]3P3O9·H2O was synthesized and characterized by X-ray diffraction. This compound crystallizes in the monoclinic space group P21/n with a = 6.803(4), b = 24.816(6), c = 17.330(2)Å, (β = 91,70(5)° and V = 2924(2)Å3. The crystal structure was determined and refined to R = 0.040 and Rw = 0.053. The atomic arrangement can be described as inorganic chains containing P3O9 rings, with the ammonium group of the organic cation [RNH3]+ and water molecules extending along the a direction. Between these chains are anchored the 2,6-dimethylanilinium groups, giving rise to a three-dimensional network.
