The material described by U3Pt5Si crystallizes in the orthorhombic Ima2 space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 9-coordinate geometry to one Pt(3), four equivalent Pt(1), and four equivalent Pt(2) atoms. In the second U site, U(2) is bonded in a 6-coordinate geometry to one Pt(3), two equivalent Pt(1), four equivalent Pt(2), and one Si(1) atom. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to one U(2), four equivalent U(1), two equivalent Pt(2), and one Si(1) atom. In the second Pt site, Pt(2) is bonded in a 11-coordinate geometry to two equivalent U(2), four equivalent U(1), one Pt(2), one Pt(3), two equivalent Pt(1), and one Si(1) atom. In the third Pt site, Pt(3) is bonded in a 5-coordinate geometry to one U(2), two equivalent U(1), two equivalent Pt(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 7-coordinate geometry to one U(2), two equivalent Pt(1), two equivalent Pt(2), and two equivalent Pt(3) atoms. is represented by the CIF file [CIF]
