  Rb3H(SeO4)2 at 4K by Neutron Powder Diffraction

  摘要：

  The monoclinic structure of trirubidium hydrogen bis[tetraoxoselenate(2-)], Rb3H(SeO4)(2), has been refined from neutron powder diffraction data collected at 4K, revealing the peculiarities of the so-called zero-dimensional hydrogen-bond network. The hydrogen bridge, with an O ... O distance of 2.473 (4) Angstrom, is non-linear [O-H ... O 173(2)degrees] with the H atom disordered between two symmetry-constrained positions of half occupancy [H ... H 0.34(3) Angstrom]. The disorder might be static.

  We have investigated the rule concerning the superprotonic phase transition temperature T-C for M3H(XO4)(2)-type superprotonic conductors. It was found that the component of spontaneous strain a(0) (=(b(m) - a(m)/root 3)/2b(m)), where a(m) and b(m) are lattice constants far below T-C is closely related to the phase transition temperature and that the superprotonic phase transition temperature obeys the equation a(0)(2) = alpha - beta T-C (alpha = 9.02 x 10(-5), beta = 1.74 x 10(-7) K-1). This result indicates that the spontaneous strain in the a(m)-b(m) plane is strongly correlated with the transition temperature T-C. Moreover, it is deduced from analysis of the free energy that this scaling rule is describing the competition between the spontaneous strain energy and the kinetic energy of the protons, that is, the energy accompanying the increase in entropy of protons in the superprotonic phase.

• Dynamics of superionic Rb3H(SeO4)2 single crystals studied by 1H and 87Rb spin–lattice relaxation

  The H-1 and Rb-87 spin-lattice relaxation and spin-spin relaxation times in superionic Rb3H(SeO4)(2) single crystals grown by the slow evaporation method were measured over the temperature range 160-450 K. The temperature dependencies of the H-1 T-1, T-1p, and T-2 are measured. In the ferroelastic phase, T-1 differs from T-1p, which is in turn different from T,, although these three relaxation times converge to similar values near 410 K. This transition seems to occur at temperature which is about 40 K lower than the superionic transition temperature. The observation of liquid-like values of the H-1 T-1, T-1p, and T-2 in the high temperature is compatible with the phase being superionic, indicating that the destruction and reconstruction of hydrogen bonds does indeed occur at high temperature. In addition, the Rb-87 T-1 and T-2 values at high temperature were similar (on the order of milliseconds), a trend that was also observed for H-1 T-1 and T-2. This behavior is expected for most hopping-type ionic conductors, and could be attributed to interactions between the mobile ions and the neighboring group ions within the crystal. The motion giving rise to this liquid-like behavior is related to the superionic motion. (c) 2005 Elsevier Inc. All rights reserved.
