The crystal structure described by Zr5Pt3 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 6-coordinate geometry to two equivalent Pt(1) and four equivalent Pt(2) atoms. In the second Zr site, Zr(2) is bonded to two equivalent Pt(2) and three equivalent Pt(1) atoms to form a mixture of distorted corner and edge-sharing ZrPt5 trigonal bipyramids. In the third Zr site, Zr(3) is bonded to one Pt(1) and four equivalent Pt(2) atoms to form a mixture of distorted corner and edge-sharing ZrPt5 trigonal bipyramids. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to two equivalent Zr(3), three equivalent Zr(2), and four equivalent Zr(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to one Zr(2), four equivalent Zr(1), and four equivalent Zr(3) atoms. is represented by the CIF file [CIF]
