摘要

At room temperature, the new compound Rb1.89Na0.11(SO4)(0.89)(SeO4).Te-011(OH)(6) crystallizes in the monoclinic system with space group P2(1)/c. The unit cell parameters are: a = 13.655 (4), b = 6.681 (4), c = 11.497 , beta = 107.07A degrees (3), V = 1002.60(5) (3), Z = 4 and rho(cal) = 3.26 g.cm(-1). The structure is stabilized by interplanar O-H center dot center dot center dot O hydrogen bonds involving all the H atoms that belong to the OH groups of the Te(OH)(6) octahedra. Raman spectra of the material recorded at various temperatures (300-500 K) in the frequency range 100-1000 cm(-1) and IR spectra achieved at room temperature between 600 and 3500 cm(-1), confirm the presence of all the phase transitions detected in the material and show that anionic groups coexist independently in the same crystal.
