The crystal structure described by YbPd5Si3 crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded in a 17-coordinate geometry to one Pd(3), one Pd(5), three equivalent Pd(1), three equivalent Pd(2), three equivalent Pd(4), two equivalent Si(1), two equivalent Si(2), and two equivalent Si(3) atoms. There are five inequivalent Pd sites. In the first Pd site, Pd(5) is bonded in a 5-coordinate geometry to one Yb(1), one Si(1), two equivalent Si(2), and two equivalent Si(3) atoms. In the second Pd site, Pd(1) is bonded in a 6-coordinate geometry to three equivalent Yb(1), one Si(2), and three equivalent Si(1) atoms. In the third Pd site, Pd(2) is bonded in a 4-coordinate geometry to three equivalent Yb(1), one Si(3), and three equivalent Si(2) atoms. In the fourth Pd site, Pd(3) is bonded in a 4-coordinate geometry to one Yb(1), one Si(2), and three equivalent Si(3) atoms. In the fifth Pd site, Pd(4) is bonded in a 4-coordinate geometry to three equivalent Yb(1), one Si(3), and three equivalent Si(1) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Yb(1), one Pd(5), three equivalent Pd(1), and three equivalent Pd(4) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to two equivalent Yb(1), one Pd(1), one Pd(3), two equivalent Pd(5), and three equivalent Pd(2) atoms.
