Ce2PtNi crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 7-coordinate geometry to four equivalent Pt(1) and three equivalent Ni(1) atoms. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to three equivalent Pt(1) and four equivalent Ni(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to three equivalent Ce(2), four equivalent Ce(1), and two equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1), four equivalent Ce(2), and two equivalent Pt(1) atoms.
Ce2PtNi crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 7-coordinate geometry to four equivalent Pt(1) and three equivalent Ni(1) atoms. All Ce(1)-Pt(1) bond lengths are 2.97 Å. There is one shorter (2.99 Å) and two longer (3.12 Å) Ce(1)-Ni(1) bond lengths. In the second Ce site, Ce(2) is bonded in a 7-coordinate geometry to three equivalent Pt(1) and four equivalent Ni(1) atoms. There are two shorter (3.05 Å) and one longer (3.07 Å) Ce(2)-Pt(1) bond length. All Ce(2)-Ni(1) bond lengths are 2.95 Å. Pt(1) is bonded in a 9-coordinate geometry to three equivalent Ce(2), four equivalent Ce(1), and two equivalent Ni(1) atoms. Both Pt(1)-Ni(1) bond lengths are 2.84 Å. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1), four equivalent Ce(2), and two equivalent Pt(1) atoms.
