The structure described by TbPdSi crystallizes in the orthorhombic Pnma space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 12-coordinate geometry to one Pd(2), two equivalent Pd(3), three equivalent Pd(1), one Si(3), two equivalent Si(1), and three equivalent Si(2) atoms. In the second Tb site, Tb(2) is bonded in a 12-coordinate geometry to one Pd(3), two equivalent Pd(2), three equivalent Pd(1), one Si(1), two equivalent Si(3), and three equivalent Si(2) atoms. In the third Tb site, Tb(3) is bonded in a 12-coordinate geometry to three equivalent Pd(2), three equivalent Pd(3), three equivalent Si(1), and three equivalent Si(3) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(3) is bonded in a 10-coordinate geometry to one Tb(2), two equivalent Tb(1), three equivalent Tb(3), one Pd(1), one Si(1), and two equivalent Si(3) atoms. In the second Pd site, Pd(1) is bonded in a 10-coordinate geometry to three equivalent Tb(1), three equivalent Tb(2), one Pd(3), and three equivalent Si(2) atoms. In the third Pd site, Pd(2) is bonded in a 10-coordinate geometry to one Tb(1), two equivalent Tb(2), three equivalent Tb(3), one Si(3), and three equivalent Si(1) atoms. There are three inequivalent Si sites.
