摘要

Two new mixed bismuth (III) tellurite nitrate/sulfate, H[Bi3O(Te3O9)](NO3)(2) and [Bi-2(TeO3)(2)](SO4) were synthesized under hydrothermal conditions. H[Bi3O(Te3O9)](NO3)(2) crystallizes in the hexagonal space group P6 2 m (No. 189) with lattice parameters a = 9.8465(4), b = 9.8465(4), c = 4.1917(4) angstrom, V = 351.95(4) angstrom(3), Z = 1, while [Bi-2(TeO3)(2])(SO4) crystallizes in the monoclinic space group C2/c (No. 15) with lattice parameters a = 15.7657(13), b = 7.4285(5), c= 8.0959(6) angstrom, beta = 112.693(2)degrees V = 874.75(11) angstrom(3), Z = 4. The structure of H[Bi3O(Te3O9)](NO3)(2) features one-dimensional cationic (1)(infinity)[Bi3O(Te3O9)](+) chains along c axis, which are composed of [BiO7] and [Teat] polyhedra by sharing corners and edges, whereas [Bi-2(TeO3)(2)](SO4) possesses a new three-dimensional framework consisting of two-dimensional zigzag layers of (2)(infinity)[Bi-2(TeO3)(2)](2+) that are linked by SO42- anions. Title compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction, Raman spectra, infrared spectra and solid state UV-vis-NIR diffuse reflectance spectroscopy.
