The material structure described by Eu5Pt4 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Eu sites. In the first Eu site, Eu(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 Eu site, Eu(2) is bonded to one Pt(2), two equivalent Pt(3), and four equivalent Pt(1) atoms to form distorted EuPt7 pentagonal bipyramids that share corners with four equivalent Eu(3)Pt6 octahedra, corners with six equivalent Eu(2)Pt7 pentagonal bipyramids, edges with two equivalent Eu(2)Pt7 pentagonal bipyramids, faces with two equivalent Eu(3)Pt6 octahedra, and faces with three equivalent Eu(2)Pt7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 46-52°. In the third Eu site, Eu(3) is bonded to two equivalent Pt(1), two equivalent Pt(2), and two equivalent Pt(3) atoms to form distorted EuPt6 octahedra that share corners with four equivalent Eu(3)Pt6 octahedra, corners with eight equivalent Eu(2)Pt7 pentagonal bipyramids, and faces with four equivalent Eu(2)Pt7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 52-54°. There are three inequivalent Pt sites. In the first Pt site, Pt(3) is bonded in a 9-coordinate geometry to two equivalent Eu(1), two equivalent Eu(3), four equivalent Eu(2), and one Pt(2) atom. In the second Pt site, Pt(1) is bonded in a 8-coordinate geometry to one Eu(3), three equivalent Eu(1), and four equivalent Eu(2) atoms. In the third Pt site, Pt(2) is bonded in a 9-coordinate geometry to two equivalent Eu(2), two equivalent Eu(3), four equivalent Eu(1), and one Pt(3) atom. is represented by the CIF card [CIF]
