The material structure described by Yb5Pt4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 6-coordinate geometry to one Pt(3), two equivalent Pt(2), and three equivalent Pt(1) atoms. In the second Yb site, Yb(2) is bonded to one Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms to form distorted YbPt7 pentagonal bipyramids that share corners with four equivalent Yb(3)Pt6 octahedra, corners with six equivalent Yb(2)Pt7 pentagonal bipyramids, edges with two equivalent Yb(2)Pt7 pentagonal bipyramids, faces with two equivalent Yb(3)Pt6 octahedra, and faces with three equivalent Yb(2)Pt7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 46-51°. In the third Yb site, Yb(3) is bonded to two equivalent Pt(1), two equivalent Pt(2), and two equivalent Pt(3) atoms to form distorted YbPt6 octahedra that share corners with four equivalent Yb(3)Pt6 octahedra, corners with eight equivalent Yb(2)Pt7 pentagonal bipyramids, and faces with four equivalent Yb(2)Pt7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 49-54°. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a 9-coordinate geometry to two equivalent Yb(1), two equivalent Yb(3), four equivalent Yb(2), and one Pt(2) atom. In the second Pt site, Pt(1) is bonded in a 8-coordinate geometry to one Yb(3), three equivalent Yb(1), and four equivalent Yb(2) atoms. In the third Pt site, Pt(2) is bonded in a 9-coordinate geometry to two equivalent Yb(2), two equivalent Yb(3), four equivalent Yb(1), and one Pt(3) atom. is represented by the CIF card [CIF]
