The material structure described by Sm2Pd3Si5 crystallizes in the orthorhombic Ibam space group. Sm(1) is bonded in a 17-coordinate geometry to two equivalent Pd(2), five equivalent Pd(1), two equivalent Si(3), four equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(2) is bonded in a 6-coordinate geometry to four equivalent Sm(1), two equivalent Si(1), and four equivalent Si(2) atoms. In the second Pd site, Pd(1) is bonded in a 5-coordinate geometry to five equivalent Sm(1), one Si(2), two equivalent Si(1), and two equivalent Si(3) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Pd(2), two equivalent Pd(1), and two equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent Sm(1), one Pd(1), two equivalent Pd(2), and two equivalent Si(1) atoms. In the third Si site, Si(3) is bonded in a 8-coordinate geometry to four equivalent Sm(1) and four equivalent Pd(1) atoms. is represented by the CIF file [CIF]
