The material 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 7-coordinate geometry to three equivalent Ce(3) and four equivalent Pt(1) atoms. In the second Ce site, Ce(3) is bonded in a 4-coordinate geometry to three equivalent Ce(1) and four equivalent Pt(1) atoms. In the third Ce site, Ce(2) is bonded in a 6-coordinate geometry to six equivalent Pt(1) atoms. Pt(1) is bonded in a 12-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), four equivalent Ce(3), and two equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
