摘要
The oxoantimonates(V) Cs2Sb4O11 (monoclinic, C2/m, a=1964.5(5), b=762.8(2), c=730.2(2) pm, beta =96.276(5)degrees, Z=4) and A(3)Sb(5)O(14) (A=Rb/Cs; orthorhombic, Pbam, a=718.81(9)/ 743.37(13), b=2447.8(2)/2625.1(5), c=733.1(2)/739.6(3) pm, Z=4) were synthesized from Sb2O5 and the peroxides AO(2) (A=Rb, CS). Their crystal structures were determined on the basis of single crystal diffractometer data. The structures are composed of three-dimensional nets of [SbO6] octahedra connected via common corners and edges, with the A cations incorporated in the resulting channel systems. The Raman spectra of the compounds are discussed in relation with the different type of oxide connectivites in the oxoantimonate anions.
