Materials Data on Y4Cu19Pb by Materials Project
Abstract
Y4Cu19Pb crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are four inequivalent Y sites. In the first Y site, Y is bonded in a 9-coordinate geometry to sixteen Cu atoms. There are a spread of Y–Cu bond distances ranging from 2.90–3.08 Å. In the second Y site, Y is bonded in a 6-coordinate geometry to fifteen Cu and one Pb atom. There are a spread of Y–Cu bond distances ranging from 2.84–3.03 Å. The Y–Pb bond length is 3.20 Å. In the third Y site, Y is bonded in a 1-coordinate geometry to thirteen Cu and three equivalent Pb atoms. There are a spread of Y–Cu bond distances ranging from 2.88–3.20 Å. All Y–Pb bond lengths are 3.18 Å. In the fourth Y site, Y is bonded in a 10-coordinate geometry to sixteen Cu atoms. There are a spread of Y–Cu bond distances ranging from 2.88–3.10 Å. There are eleven inequivalent Cu sites. In the first Cu site, Cu is bonded in a 4-coordinate geometry to four Y and twelve Cu atoms. There are nine shorter (2.91 Å) and three longer (2.97 Å) Cu–Cu bond lengths. In the second Cu site, Cu is bonded in amore »
