Abstract
Polymorphism of crystalline DClO4·2D2O with 99 at % D has been studied by IR absorption spectroscopy. A new phase has been found, which is easy to identify based on some spectral indications: the spectra show a strong broad band at 2125 cm−1 due to vs,as(D3O) vibrations of the deuterodioxonium group and a rather narrow strong band at 2506 cm−1 due to the vas(D2O) vibrations of the neutral molecular group. The continuous band vas(O...D...O) typical of the intracationic hydrogen bond in D5O +2 ClO −4 is absent in this case. These features point to considerable polarization of the deuterooxonium cation [D2O...D-OD2]+. Its low symmetry is explained by a considerable displacement of the bridging D atom from the center of the strong hydrogen bond to one of the two D2O molecules induced by asymmetric interactions in the crystal field. The ClO −4 ions bound by the hydrogen bonds of dioxonium are also in low-symmetry positions. Upon the crystallization of DClO4·2D2O with ≥10 at % H, a polymorphic isotope effect is observed: the crystal structure depends on H-D isotope dilution, the conditions of thermal treatment of all samples being the same.
