Rb2Sb4O11

Rb2Sb4O11
Rb2Sb4O11
The title compound, dirubidium tetraantimonate(V), Rb2Sb4O11, has been synthesized by flux reaction. It is isotypic with known A2Sb4O11 (A = K, Cs) structures and consists of an (Sb4O11)2- skeleton and two Rb atoms as charge-compensating cations. Distorted SbO6 octahedra share edges and corners, resulting in a layered assembly. Alternate stacking of the layers along the c axis leads to the formation of tunnels. The Rb+ ions, surrounded by nine and ten O atoms, respectively, are located in these tunnels. Some atoms in the structure are on special positions of m symmetry (two Sb atoms, both Rb atoms and four O atoms) and 2 symmetry (one O atom)

Abstract

The title compound, dirubidium tetraantimonate(V), Rb2Sb4O11, has been synthesized by flux reaction. It is isotypic with known A2Sb4O11 (A = K, Cs) structures and consists of an (Sb4O11)2- skeleton and two Rb atoms as charge-compensating cations. Distorted SbO6 octahedra share edges and corners, resulting in a layered assembly. Alternate stacking of the layers along the c axis leads to the formation of tunnels. The Rb+ ions, surrounded by nine and ten O atoms, respectively, are located in these tunnels. Some atoms in the structure are on special positions of m symmetry (two Sb atoms, both Rb atoms and four O atoms) and 2 symmetry (one O atom)
