The crystal structure described by Eu2Pt3Si5 crystallizes in the orthorhombic Ibam space group. Eu(1) is bonded in a 17-coordinate geometry to two equivalent Pt(1), five equivalent Pt(2), two equivalent Si(1), four equivalent Si(2), and four equivalent Si(3) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to four equivalent Eu(1), two equivalent Si(2), and four equivalent Si(3) atoms. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to five equivalent Eu(1), one Si(3), two equivalent Si(1), and two equivalent Si(2) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1) and four equivalent Pt(2) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Pt(1), two equivalent Pt(2), and two equivalent Si(3) atoms. In the third Si site, Si(3) is bonded in a 9-coordinate geometry to four equivalent Eu(1), one Pt(2), two equivalent Pt(1), and two equivalent Si(2) atoms. is represented by the CIF file [CIF]
