Sc(Fe2Si)2 crystallizes in the tetragonal P4_2/mnm space group. Sc(1) is bonded in a 18-coordinate geometry to twelve equivalent Fe(1) and six equivalent Si(1) atoms. Fe(1) is bonded in a 3-coordinate geometry to three equivalent Sc(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Fe(1) atoms.
Sc(Fe2Si)2 crystallizes in the tetragonal P4_2/mnm space group. Sc(1) is bonded in a 18-coordinate geometry to twelve equivalent Fe(1) and six equivalent Si(1) atoms. There are four shorter (3.00 Å) and eight longer (3.13 Å) Sc(1)-Fe(1) bond lengths. There are two shorter (2.75 Å) and four longer (2.83 Å) Sc(1)-Si(1) bond lengths. Fe(1) is bonded in a 3-coordinate geometry to three equivalent Sc(1) and three equivalent Si(1) atoms. There is one shorter (2.31 Å) and two longer (2.35 Å) Fe(1)-Si(1) bond lengths. Si(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Fe(1) atoms.
