Materials Data on YbMgPb by Materials Project

Abstract

YbMgPb crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a distorted trigonal planar geometry to six Yb and three Pb atoms. There are four shorter (3.33 Å) and two longer (3.34 Å) Mg–Yb bond lengths. There are one shorter (3.04 Å) and two longer (3.05 Å) Mg–Pb bond lengths. In the second Mg site, Mg is bonded in a 9-coordinate geometry to three Yb and six Pb atoms. All Mg–Yb bond lengths are 3.25 Å. There are two shorter (3.16 Å) and four longer (3.17 Å) Mg–Pb bond lengths. There are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 11-coordinate geometry to five Mg and six Pb atoms. There are two shorter (3.48 Å) and four longer (3.55 Å) Yb–Pb bond lengths. In the second Yb site, Yb is bonded in a 11-coordinate geometry to five Mg and six Pb atoms. There are two shorter (3.46 Å) and four longer (3.56 Å) Yb–Pb bond lengths. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 10-coordinate geometry to four Mg and six Yb atoms. In the second Pb site, Pb is bonded in a 10-coordinate geometry to four Mg and six Yb atoms.
