The crystal structure described by Tb3Zn11 crystallizes in the orthorhombic Immm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to four equivalent Zn(2), four equivalent Zn(4), and eight equivalent Zn(3) atoms to form distorted TbZn16 cuboctahedra that share corners with four equivalent Zn(1)Zn8 cuboctahedra, faces with two equivalent Tb(1)Zn16 cuboctahedra, and faces with two equivalent Zn(1)Zn8 cuboctahedra. In the second Tb site, Tb(2) is bonded in a 14-coordinate geometry to two equivalent Zn(2), six equivalent Zn(3), and six equivalent Zn(4) atoms. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to four equivalent Zn(2) and four equivalent Zn(4) atoms to form distorted ZnZn8 cuboctahedra that share corners with four equivalent Tb(1)Zn16 cuboctahedra, edges with two equivalent Zn(1)Zn8 cuboctahedra, and faces with two equivalent Tb(1)Zn16 cuboctahedra. In the second Zn site, Zn(2) is bonded in a 13-coordinate geometry to two equivalent Tb(1), two equivalent Tb(2), one Zn(2), two equivalent Zn(1), two equivalent Zn(3), and four equivalent Zn(4) atoms. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to two equivalent Tb(1), three equivalent Tb(2), one Zn(2), one Zn(3), and three equivalent Zn(4) atoms. In the fourth Zn site, Zn(4) is bonded in a 10-coordinate geometry to one Tb(1), three equivalent Tb(2), one Zn(1), two equivalent Zn(2), and three equivalent Zn(3) atoms. is represented by the CIF file [CIF]
