ResumoThe structure of RbCdCl3has been determined from X-ray diffraction of the MoKα line (λ = 0.7107 Å) for a single crystal grown at room temperature from aqueous solution. After refinement through blocked least-squares methods, the reliability factorRin the final cycle was 3.31%, using 1955 observed reflections withI≥ 2σ(I). The following results have been obtained, in good agreement with previous powder measurements:orthorhombic system, space groupPnma(D2h),a= 8.962 Å,b= 4.034 Å,c= 14.980 Å;Dm= 3.732 g/cm3,Dx= 3.736 g/cm3,F(000) = 543.90;Z= 4. Double columns of edge-sharing CdCl6octahedra (Cd–Cl = 2.647 Å) extending alongbare linked by nine coordinated Rb ions (Rb–Cl = 3.366 Å) into a compact structure.
