摘要: Abstract Low-temperature rubidium samarium dimolybdate, β-RbSm(MoO4)2, microplates have been prepared by solid state synthesis at 723 K 70 h and 893 K 150 h. The crystal structure of β-RbSm(MoO4)2 has first refined the Rietveld method in space group Pbcn with unit cell parameters a=5.1431(2) A, b=18.8195(7) c=8.1641(3) A (RB=4.82%). consists layers MoO4 tetrahedrons corner-sharing SmO8 square antiprisms. About 20 narrow Raman lines observed spectra recorded for powder sample.
