Three compounds ASb(2)(SO4)(2)(PO4) (A = H3O+, K, Rb) were obtained from the reactions of Sb2O3, A(2)CO(3) (A = Li, Rb) or K2SO4 and NH4H2PO4 in H2SO4 (98%) at 220-250 degrees C. Their structures were determined by single-crystal X-ray diffraction. All compounds crystallize in the triclinic space group P$\bar{1}$ (no.2) and are isostructural. The crystal structures consist of two-dimensional (2)[Sb-2(SO4)(2)(PO4)](-) anionic layers and alkali cations, which are located between anionic layers. The anionic layers are composed of [SbO4] -trigonal bipyramids, [SbO5] octahedra, [SO4] tetrahedra, and [PO4] tetrahedra. All compounds are characterized by solid state UV/Vis/NIR diffuse reflectance spectra, FT-IR spectroscopy, and Raman spectroscopy.
