The compound described by Y3Pd2Si3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 10-coordinate geometry to four equivalent Pd(1), two equivalent Si(1), and five equivalent Si(2) atoms. In the second Y site, Y(2) is bonded in a 9-coordinate geometry to four equivalent Pd(1), two equivalent Si(2), and three equivalent Si(1) atoms. Pd(1) is bonded in a 10-coordinate geometry to two equivalent Y(2), four equivalent Y(1), one Si(1), and three 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 three equivalent Y(2), four equivalent Y(1), and two equivalent Pd(1) atoms. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to one Y(2), five equivalent Y(1), three equivalent Pd(1), and one Si(2) atom. is represented by the CIF card [CIF]
