  Structural and vibrational study of a new mixed dipotassium hydrogenselenate dihydrogenphosphate K2(HSeO4)1.5(H2PO4)0.5

  摘要：

  Ongoing studies of the KHSeO4-KE2PO4 system, aimed at developing novel proton conducting solids, resulted in the new compound K-2(HSeO4)(1.5)(H2PO4)(0.5) (dipotassium hydrogenselenate dihydrogen phosphate). The crystals have been prepared by slow evaporation of an aqueous solution at room temperature. The structural properties of the crystals were characterized by X-ray single analysis (performed at room temperature), which revealed that K-2(HSeO4)(1.5)(H2PO4)(0.5) (KHSeP) crystallizes in space group P (1) over bar with lattice parameters: a= 7.417(3) angstrom, b = 7.668(2) angstrom, c = 7.744(5) angstrom, alpha = 71.59(3)degrees, beta = 87.71(4)degrees and gamma = 86.04(6)degrees. The compound has a unit cell volume 416.8(3) angstrom(3) and two formula units per cell, giving a calculated density of 2.732. The structure was solved from 3210 independent reflections and refined with 112 parameters yielded weighted residuals of 0.1113 and 0.0594 based on F-2 and F values, respectively. This structure is characterized by HSeO4- and disordered (HxSe/P)O-4(-) tetrahedra connected to dimmer via hydrogen bridges. These dimmers are linked and stabilized by an additional hydrogen bonds (O-H-O) and hydrogen bonds (O-H... O) to built a chains of dimmers, which are parallel to the [0 10] direction at the position x = 0.5. The potassium atoms have an eight-fold coordination.The infrared spectrum at room temperature is investigated in the frequency range 4000-400 cm(-1) and confirm a structural disorder in this material and the coexistence of two different anions (H2PO4- and HSeO4-) in the same crystal structure.

  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.
