Yb5Cu11Sn8 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are three inequivalent Yb sites. In the first Yb site, Yb is bonded in a 2-coordinate geometry to ten Cu and six Sn atoms. There are a spread of Yb–Cu bond distances ranging from 3.00–3.50 Å. There are a spread of Yb–Sn bond distances ranging from 3.10–3.31 Å. In the second Yb site, Yb is bonded in a 3-coordinate geometry to eight Cu and eight Sn atoms. There are a spread of Yb–Cu bond distances ranging from 3.07–3.50 Å. There are a spread of Yb–Sn bond distances ranging from 3.17–3.73 Å. In the third Yb site, Yb is bonded in a 12-coordinate geometry to seven Cu and seven Sn atoms. There are a spread of Yb–Cu bond distances ranging from 3.03–3.34 Å. There are a spread of Yb–Sn bond distances ranging from 3.27–3.58 Å. There are six inequivalent Cu sites. In the first Cu site, Cu is bonded in a 8-coordinate geometry to four Yb and four Sn atoms. There are a spread of Cu–Sn bond distances ranging from 2.65–2.70 Å. In the second Cu site, Cu is bonded in a 8-coordinate geometry to four Yb and four Sn atoms. There are a spread of Cu–Sn bond distances ranging from 2.62–2.75 Å. In the third Cu site, Cu is bonded in a distorted body-centered cubic geometry to four Yb and four Sn atoms. There are two shorter (2.56 Å) and two longer (2.73 Å) Cu–Sn bond lengths. In the fourth Cu site, Cu is bonded in a 10-coordinate geometry to three Yb, three Cu, and four Sn atoms. There are one shorter (2.47 Å) and two longer (2.60 Å) Cu–Cu bond lengths. There are a spread of Cu–Sn bond distances ranging from 2.64–2.79 Å. In the fifth Cu site, Cu is bonded in a 8-coordinate geometry to three equivalent Yb, one Cu, and four Sn atoms. The Cu–Cu bond length is 2.53 Å. There are a spread of Cu–Sn bond distances ranging from 2.61–2.65 Å. In the sixth Cu site, Cu is bonded in a 10-coordinate geometry to four Yb, three Cu, and three Sn atoms. There are one shorter (2.60 Å) and two longer (2.63 Å) Cu–Sn bond lengths. There are five inequivalent Sn sites. In the first Sn site, Sn is bonded in a 9-coordinate geometry to five Yb and five Cu atoms. In the second Sn site, Sn is bonded in a 10-coordinate geometry to four Yb, five Cu, and one Sn atom. The Sn–Sn bond length is 3.07 Å. In the third Sn site, Sn is bonded in a 9-coordinate geometry to four Yb, six Cu, and one Sn atom. In the fourth Sn site, Sn is bonded to five Yb, six Cu, and one Sn atom to form distorted face-sharing SnYb5Cu6Sn cuboctahedra. The Sn–Sn bond length is 2.88 Å. In the fifth Sn site, Sn is bonded in a 10-coordinate geometry to five Yb, four Cu, and one Sn atom.
