The material described by Eu5Pt2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 2-coordinate geometry to three equivalent Pt(1) atoms. In the second Eu site, Eu(3) is bonded to four equivalent Pt(1) atoms to form distorted edge-sharing EuPt4 tetrahedra. In the third Eu site, Eu(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Eu(3), three equivalent Eu(1), and three equivalent Eu(2) atoms. is represented by the CIF file [CIF]
