Materials Data on Rb3Sr by Materials Project
Rb3Sr is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to eight equivalent Rb and four equivalent Sr atoms to form RbRb8Sr4 cuboctahedra that share corners with twelve equivalent RbRb8Sr4 cuboctahedra, edges with eight equivalent SrRb12 cuboctahedra, edges with sixteen equivalent RbRb8Sr4 cuboctahedra, faces with four equivalent SrRb12 cuboctahedra, and faces with fourteen equivalent RbRb8Sr4 cuboctahedra. All Rb–Rb bond lengths are 4.83 Å. All Rb–Sr bond lengths are 4.83 Å. Sr is bonded to twelve equivalent Rb atoms to form SrRb12 cuboctahedra that share corners with twelve equivalent SrRb12 cuboctahedra, edges with twenty-four equivalent RbRb8Sr4 cuboctahedra, faces with six equivalent SrRb12 cuboctahedra, and faces with twelve equivalent RbRb8Sr4 cuboctahedra.
