Materials Data on SmGd(MnNi4)2 by Materials Project
Abstract
GdSm(MnNi4)2 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. Gd is bonded in a 6-coordinate geometry to three Mn and fifteen Ni atoms. There are one shorter (2.87 Å) and two longer (2.88 Å) Gd–Mn bond lengths. There are a spread of Gd–Ni bond distances ranging from 2.87–3.18 Å. Sm is bonded in a 6-coordinate geometry to three Mn and fifteen Ni atoms. There are two shorter (2.88 Å) and one longer (2.89 Å) Sm–Mn bond lengths. There are three shorter (2.89 Å) and twelve longer (3.18 Å) Sm–Ni bond lengths. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded to one Gd, two equivalent Sm, and nine Ni atoms to form distorted MnSm2GdNi9 cuboctahedra that share corners with twenty-one NiSmGd2Mn3Ni6 cuboctahedra, edges with six MnSm2GdNi9 cuboctahedra, faces with two equivalent MnSm2GdNi9 cuboctahedra, and faces with twenty-one NiSmGd2Mn3Ni6 cuboctahedra. There are a spread of Mn–Ni bond distances ranging from 2.45–2.89 Å. In the second Mn site, Mn is bonded to two equivalent Gd, one Sm, and nine Ni atoms to form distorted MnSmGd2Ni9 cuboctahedra that share corners with twenty-one NiSmGd2Mn3Ni6 cuboctahedra, edges with six MnSm2GdNi9 cuboctahedra, faces with two equivalent MnSmGd2Ni9 cuboctahedra,more »
