The material described by Sm(Re2Si)2 crystallizes in the tetragonal P4_2/mnm space group. Sm(1) is bonded in a 18-coordinate geometry to twelve equivalent Re(1) and six equivalent Si(1) atoms. Re(1) is bonded to three equivalent Sm(1), six equivalent Re(1), and three equivalent Si(1) atoms to form a mixture of distorted edge, face, and corner-sharing ReSm3Re6Si3 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Re(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
