The compound described by Sm4Pd4Si3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 11-coordinate geometry to two equivalent Pd(1), five equivalent Pd(2), one Si(2), and three equivalent Si(1) atoms. In the second Sm site, Sm(2) is bonded in a 8-coordinate geometry to one Pd(2), four equivalent Pd(1), two equivalent Si(1), and three equivalent Si(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to two equivalent Sm(1), four equivalent Sm(2), one Si(1), and two equivalent Si(2) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to one Sm(2), five equivalent Sm(1), and three equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to two equivalent Sm(2), three equivalent Sm(1), one Pd(1), and three equivalent Pd(2) atoms. In the second Si site, Si(2) is bonded in a 12-coordinate geometry to two equivalent Sm(1), six equivalent Sm(2), and four equivalent Pd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
