The structure described by TbZn3 crystallizes in the orthorhombic Pnma space group. Tb(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 Tb(1), two equivalent Zn(1), and three equivalent Zn(3) atoms. In the second Zn site, Zn(1) is bonded in a 12-coordinate geometry to five equivalent Tb(1), two equivalent Zn(1), two equivalent Zn(2), and three equivalent Zn(3) atoms. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to four equivalent Tb(1), three equivalent Zn(1), and three equivalent Zn(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
