Crystal Structure and Physicochemical Properties of a New 4,4′-Diammoniumdiphenylether Triphosphate [C12H14N2O]2HP3O10•2H2O

Crystals of 4,4'-diammoniumdiphenylether triphosphate, [C12H14N2O](2)HP3O10 center dot 2H(2)O (1), were prepared and grown at room temperature. Species 1 crystallizes in the triclinic system with centric space group . Its unit cell dimensions are a = 10.487(2), b = 10.766(2), c = 15.553(2) , alpha = 98.53(1)A degrees, beta = 107.55(1)A degrees, gamma = 103.31(2), with V = 1588.8(5) (3) and Z = 2. The structure was determined by X-ray data collection on a single-crystal and gives a clear description of hydrogen bonds interconnecting the triphosphoric groups so as to build [(HP3O10)(2)(H2O)](8-) infinite inorganic chains that extend along the [110] direction. Organic cations, spreading along the [101] direction establish hydrogen bonding connections between the inorganic chains. The IR spectrum for the crystal confirms that most of the vibrational modes are comparable to similar triphosphates. The thermal properties reveal that the compound is stable to 90 A degrees C.
