The crystal structure described by Ce4PtNi3 crystallizes in the orthorhombic Pmm2 space group. There are four inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 7-coordinate geometry to one Pt(1), two equivalent Ni(1), and four equivalent Ni(2) atoms. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to two equivalent Pt(1), one Ni(1), and four equivalent Ni(3) atoms. In the third Ce site, Ce(3) is bonded in a 7-coordinate geometry to four equivalent Pt(1), one Ni(2), and two equivalent Ni(3) atoms. In the fourth Ce site, Ce(4) is bonded in a 7-coordinate geometry to one Ni(3), two equivalent Ni(2), and four equivalent Ni(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to one Ce(1), two equivalent Ce(2), four equivalent Ce(3), and two equivalent Ni(3) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), four equivalent Ce(4), and two equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to one Ce(3), two equivalent Ce(4), four equivalent Ce(1), and two equivalent Ni(1) atoms. In the third Ni site, Ni(3) is bonded in a 9-coordinate geometry to one Ce(4), two equivalent Ce(3), four equivalent Ce(2), and two equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
