The compound described by MgCePt crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Pt(2) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to two equivalent Pt(1) and two equivalent Pt(2) atoms. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 5-coordinate geometry to one Pt(2) and four equivalent Pt(1) atoms. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to one Pt(2) and four equivalent Pt(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to one Mg(1), two equivalent Mg(2), two equivalent Ce(2), and four equivalent Ce(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to two equivalent Mg(1), four equivalent Mg(2), one Ce(2), and two equivalent Ce(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
