Abstract

Eu3Cu8Sn4 is Hexagonal Laves-derived structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to eight Cu and six Sn atoms. There are a spread of Eu–Cu bond distances ranging from 3.22–3.59 Å. There are a spread of Eu–Sn bond distances ranging from 3.30–3.40 Å. There are four inequivalent Cu sites. In the first Cu site, Cu is bonded to two equivalent Eu, seven Cu, and three equivalent Sn atoms to form distorted CuEu2Cu7Sn3 cuboctahedra that share corners with four equivalent CuEu2Cu7Sn3 cuboctahedra, corners with five equivalent SnEu4Cu8 cuboctahedra, faces with six equivalent SnEu4Cu8 cuboctahedra, and faces with eight CuEu2Cu7Sn3 cuboctahedra. There are a spread of Cu–Cu bond distances ranging from 2.51–2.77 Å. There are one shorter (2.70 Å) and two longer (2.75 Å) Cu–Sn bond lengths. In the second Cu site, Cu is bonded to nine Cu and three equivalent Sn atoms to form CuCu9Sn3 cuboctahedra that share corners with three equivalent SnEu4Cu8 cuboctahedra, faces with six equivalent SnEu4Cu8 cuboctahedra, and faces with eight CuEu2Cu7Sn3 cuboctahedra. All Cu–Cu bond lengths are 2.63 Å. All Cu–Sn bond lengths are 2.74 Å. In the third Cu site, Cu is bonded inmore »« less
