The compound described by Ce7Pt3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. In the second Ce site, Ce(3) is bonded in a 2-coordinate geometry to four equivalent Pt(1) atoms. In the third Ce site, Ce(2) is bonded in a 3-coordinate geometry to four equivalent Pt(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to one Ce(1), four equivalent Ce(2), and four equivalent Ce(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
