Materials Data on PrSm(Co2Ni3)2 by Materials Project
Abstract
SmPr(Co2Ni3)2 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. Sm is bonded in a 6-coordinate geometry to six Co and twelve Ni atoms. There are two shorter (2.85 Å) and four longer (2.86 Å) Sm–Co bond lengths. There are eight shorter (3.18 Å) and four longer (3.19 Å) Sm–Ni bond lengths. Pr is bonded in a 6-coordinate geometry to six Co and twelve Ni atoms. All Pr–Co bond lengths are 2.87 Å. There are four shorter (3.19 Å) and eight longer (3.20 Å) Pr–Ni bond lengths. There are two inequivalent Co sites. In the first Co site, Co is bonded in a 12-coordinate geometry to two equivalent Sm, one Pr, and six Ni atoms. There are two shorter (2.46 Å) and four longer (2.47 Å) Co–Ni bond lengths. In the second Co site, Co is bonded in a 12-coordinate geometry to one Sm, two equivalent Pr, and six Ni atoms. There are four shorter (2.46 Å) and two longer (2.47 Å) Co–Ni bond lengths. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded to four equivalent Pr, four equivalent Co, and four equivalent Ni atoms to form NiPr4Co4Ni4 cuboctahedra that share cornersmore »
