Materials Data on Ce2(MnNi)5 by Materials Project
Abstract
Ce2(MnNi)5 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 6-coordinate geometry to six Mn and twelve Ni atoms. There are four shorter (2.95 Å) and two longer (2.99 Å) Ce–Mn bond lengths. All Ce–Ni bond lengths are 3.25 Å. In the second Ce site, Ce is bonded in a 6-coordinate geometry to ten Mn and eight equivalent Ni atoms. There are six shorter (2.92 Å) and four longer (3.25 Å) Ce–Mn bond lengths. All Ce–Ni bond lengths are 3.21 Å. There are three inequivalent Mn sites. In the first Mn site, Mn is bonded in a 12-coordinate geometry to three Ce, two equivalent Mn, and four equivalent Ni atoms. Both Mn–Mn bond lengths are 2.44 Å. All Mn–Ni bond lengths are 2.50 Å. In the second Mn site, Mn is bonded in a 12-coordinate geometry to three Ce and six Ni atoms. There are two shorter (2.48 Å) and four longer (2.49 Å) Mn–Ni bond lengths. In the third Mn site, Mn is bonded to four equivalent Ce, four equivalent Mn, and four equivalent Ni atoms to form distorted MnCe4Mn4Ni4 cuboctahedramore »
