LuZn3 crystallizes in the orthorhombic Pnma space group. Lu(1) is bonded in a 14-coordinate geometry to four equivalent Zn(3), five equivalent Zn(1), and five equivalent Zn(2) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(2) is bonded in a 10-coordinate geometry to five equivalent Lu(1), two equivalent Zn(1), and three equivalent Zn(3) atoms. In the second Zn site, Zn(1) is bonded to five equivalent Lu(1), two equivalent Zn(1), two equivalent Zn(2), and three equivalent Zn(3) atoms to form a mixture of distorted corner and face-sharing ZnLu5Zn7 cuboctahedra. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to four equivalent Lu(1), three equivalent Zn(1), and three equivalent Zn(2) atoms.
LuZn3 crystallizes in the orthorhombic Pnma space group. Lu(1) is bonded in a 14-coordinate geometry to four equivalent Zn(3), five equivalent Zn(1), and five equivalent Zn(2) atoms. There are a spread of Lu(1)-Zn(3) bond distances ranging from 2.92-3.12 Å. There are a spread of Lu(1)-Zn(1) bond distances ranging from 3.03-3.35 Å. There are a spread of Lu(1)-Zn(2) bond distances ranging from 2.90-3.23 Å. There are three inequivalent Zn sites. In the first Zn site, Zn(2) is bonded in a 10-coordinate geometry to five equivalent Lu(1), two equivalent Zn(1), and three equivalent Zn(3) atoms. There is one shorter (2.55 Å) and one longer (2.58 Å) Zn(2)-Zn(1) bond length. There are two shorter (2.53 Å) and one longer (2.71 Å) Zn(2)-Zn(3) bond length. In the second Zn site, Zn(1) is bonded to five equivalent Lu(1), two equivalent Zn(1), two equivalent Zn(2), and three equivalent Zn(3) atoms to form a mixture of distorted corner and face-sharing ZnLu5Zn7 cuboctahedra. Both Zn(1)-Zn(1) bond lengths are 2.97 Å. There is one shorter (2.54 Å) and two longer (2.72 Å) Zn(1)-Zn(3) bond lengths. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to four equivalent Lu(1), three equivalent Zn(1), and three equivalent Zn(2) atoms.
