The material structure described by Tb2CuZnSi2 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded to two equivalent Cu(1), four equivalent Zn(1), two equivalent Si(2), and four equivalent Si(1) atoms to form TbZn4Cu2Si6 cuboctahedra that share edges with four equivalent Tb(1)Zn4Cu2Si6 cuboctahedra, edges with eight equivalent Tb(2)Zn2Cu4Si6 cuboctahedra, faces with four equivalent Tb(2)Zn2Cu4Si6 cuboctahedra, and faces with four equivalent Tb(1)Zn4Cu2Si6 cuboctahedra. In the second Tb site, Tb(2) is bonded to four equivalent Cu(1), two equivalent Zn(1), two equivalent Si(1), and four equivalent Si(2) atoms to form TbZn2Cu4Si6 cuboctahedra that share edges with four equivalent Tb(2)Zn2Cu4Si6 cuboctahedra, edges with eight equivalent Tb(1)Zn4Cu2Si6 cuboctahedra, faces with four equivalent Tb(2)Zn2Cu4Si6 cuboctahedra, and faces with four equivalent Tb(1)Zn4Cu2Si6 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to two equivalent Tb(1), four equivalent Tb(2), one Si(2), and two equivalent Si(1) atoms. Zn(1) is bonded in a distorted trigonal planar geometry to two equivalent Tb(2), four equivalent Tb(1), one Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Tb(2), four equivalent Tb(1), two equivalent Cu(1), and one Zn(1) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), four equivalent Tb(2), one Cu(1), and two equivalent Zn(1) atoms. is represented by the CIF card [CIF]
