Title: Materials Data on Tb4Cu7Sn11 by Materials Project

Abstract

Tb4Cu7Sn11 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. there are four inequivalent Tb sites. In the first Tb site, Tb is bonded to four equivalent Cu and eight Sn atoms to form a mixture of corner and face-sharing TbCu4Sn8 cuboctahedra. All Tb–Cu bond lengths are 3.09 Å. There are four shorter (3.19 Å) and four longer (3.26 Å) Tb–Sn bond lengths. In the second Tb site, Tb is bonded to five Cu and eight Sn atoms to form a mixture of distorted corner and face-sharing TbCu5Sn8 cuboctahedra. There are four shorter (3.16 Å) and one longer (3.35 Å) Tb–Cu bond lengths. There are four shorter (3.23 Å) and four longer (3.26 Å) Tb–Sn bond lengths. In the third Tb site, Tb is bonded in a 12-coordinate geometry to eight Cu and eight Sn atoms. There are four shorter (3.33 Å) and four longer (3.39 Å) Tb–Cu bond lengths. There are four shorter (3.33 Å) and four longer (3.49 Å) Tb–Sn bond lengths. In the fourth Tb site, Tb is bonded in a 4-coordinate geometry to twelve Cu and four equivalent Sn atoms. There are a spread of Tb–Cu bond distances ranging from 3.12–3.36 Å. All Tb–Snmore » bond lengths are 3.51 Å. There are five inequivalent Cu sites. In the first Cu site, Cu is bonded in a 9-coordinate geometry to four equivalent Tb and five Sn atoms. There are one shorter (2.47 Å) and four longer (2.61 Å) Cu–Sn bond lengths. In the second Cu site, Cu is bonded in a 9-coordinate geometry to four equivalent Tb, one Cu, and four equivalent Sn atoms. The Cu–Cu bond length is 2.36 Å. All Cu–Sn bond lengths are 2.66 Å. In the third Cu site, Cu is bonded in a 10-coordinate geometry to five Tb and five Cu atoms. All Cu–Cu bond lengths are 2.46 Å. In the fourth Cu site, Cu is bonded in a 12-coordinate geometry to four Tb and four Sn atoms. There are two shorter (2.59 Å) and two longer (2.69 Å) Cu–Sn bond lengths. In the fifth Cu site, Cu is bonded in a 8-coordinate geometry to four Tb, two equivalent Cu, and two equivalent Sn atoms. Both Cu–Sn bond lengths are 2.64 Å. There are seven inequivalent Sn sites. In the first Sn site, Sn is bonded in a 2-coordinate geometry to two equivalent Tb, two equivalent Cu, and five Sn atoms. There are one shorter (2.92 Å) and four longer (3.12 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a 9-coordinate geometry to two equivalent Tb, two equivalent Cu, and five Sn atoms. There are one shorter (2.97 Å) and four longer (3.12 Å) Sn–Sn bond lengths. In the third Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Tb and four equivalent Cu atoms. In the fourth Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Tb and four equivalent Cu atoms. In the fifth Sn site, Sn is bonded in a 7-coordinate geometry to two equivalent Tb and five Sn atoms. All Sn–Sn bond lengths are 3.12 Å. In the sixth Sn site, Sn is bonded in a 7-coordinate geometry to two equivalent Tb and five Sn atoms. All Sn–Sn bond lengths are 3.12 Å. In the seventh Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Tb and five Cu atoms.« less
