Materials Data on Nd2(CuAg)5 by Materials Project
Abstract
Nd2(AgCu)5 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are two inequivalent Nd sites. In the first Nd site, Nd is bonded in a 6-coordinate geometry to ten Ag and eight equivalent Cu atoms. There are a spread of Nd–Ag bond distances ranging from 3.12–3.46 Å. All Nd–Cu bond lengths are 3.55 Å. In the second Nd site, Nd is bonded in a distorted hexagonal planar geometry to six Ag and twelve Cu atoms. There are two shorter (3.02 Å) and four longer (3.06 Å) Nd–Ag bond lengths. There are eight shorter (3.45 Å) and four longer (3.46 Å) Nd–Cu bond lengths. There are three inequivalent Ag sites. In the first Ag site, Ag is bonded in a 12-coordinate geometry to three Nd, two equivalent Ag, and six Cu atoms. Both Ag–Ag bond lengths are 3.01 Å. There are four shorter (2.69 Å) and two longer (2.73 Å) Ag–Cu bond lengths. In the second Ag site, Ag is bonded in a 12-coordinate geometry to three Nd, five Ag, and four equivalent Cu atoms. There are two shorter (2.80 Å) and one longer (3.35 Å) Ag–Ag bond lengths. All Ag–Cu bond lengths are 2.71 Å. In themore »
