Tb2Ni2Sn crystallizes in the orthorhombic Immm space group. Tb(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1), one Ni(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Tb(1) and four equivalent Ni(1) atoms to form a mixture of face and edge-sharing SnTb8Ni4 cuboctahedra.
Tb2Ni2Sn crystallizes in the orthorhombic Immm space group. Tb(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. All Tb(1)-Ni(1) bond lengths are 2.96 Å. There are two shorter (3.26 Å) and two longer (3.28 Å) Tb(1)-Sn(1) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1), one Ni(1), and two equivalent Sn(1) atoms. The Ni(1)-Ni(1) bond length is 2.38 Å. Both Ni(1)-Sn(1) bond lengths are 2.68 Å. Sn(1) is bonded to eight equivalent Tb(1) and four equivalent Ni(1) atoms to form a mixture of face and edge-sharing SnTb8Ni4 cuboctahedra.
