U2Fe2Sn crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 10-coordinate geometry to six equivalent Fe(1) and four equivalent Sn(1) atoms. Fe(1) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent U(1) and four equivalent Fe(1) atoms to form a mixture of distorted corner and face-sharing SnU8Fe4 cuboctahedra.
U2Fe2Sn crystallizes in the tetragonal P4/mbm space group. U(1) is bonded in a 10-coordinate geometry to six equivalent Fe(1) and four equivalent Sn(1) atoms. There are two shorter (2.70 Å) and four longer (2.82 Å) U(1)-Fe(1) bond lengths. All U(1)-Sn(1) bond lengths are 3.26 Å. Fe(1) is bonded in a 8-coordinate geometry to six equivalent U(1) and two equivalent Sn(1) atoms. Both Fe(1)-Sn(1) bond lengths are 2.90 Å. Sn(1) is bonded to eight equivalent U(1) and four equivalent Fe(1) atoms to form a mixture of distorted corner and face-sharing SnU8Fe4 cuboctahedra.
