Abstract
Cu3Zn crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are five inequivalent Cu sites. In the first Cu site, Cu is bonded to nine Cu and three equivalent Zn atoms to form CuZn3Cu9 cuboctahedra that share corners with twelve CuZn3Cu9 cuboctahedra, edges with six equivalent ZnZn6Cu6 cuboctahedra, edges with eighteen CuZn3Cu9 cuboctahedra, faces with six equivalent ZnZn6Cu6 cuboctahedra, and faces with twelve CuZn3Cu9 cuboctahedra. There are three shorter (2.55 Å) and six longer (2.62 Å) Cu–Cu bond lengths. All Cu–Zn bond lengths are 2.60 Å. In the second Cu site, Cu is bonded to twelve Cu atoms to form CuCu12 cuboctahedra that share corners with six equivalent CuCu12 cuboctahedra, corners with six equivalent ZnZn6Cu6 cuboctahedra, edges with six equivalent ZnZn6Cu6 cuboctahedra, edges with eighteen CuZn3Cu9 cuboctahedra, and faces with eighteen CuZn3Cu9 cuboctahedra. All Cu–Cu bond lengths are 2.62 Å. In the third Cu site, Cu is bonded to nine Cu and three equivalent Zn atoms to form CuZn3Cu9 cuboctahedra that share corners with seventeen CuZn3Cu9 cuboctahedra, edges with six equivalent ZnZn6Cu6 cuboctahedra, edges with sixteen CuZn3Cu9 cuboctahedra, faces with six equivalent ZnZn6Cu6 cuboctahedra, and faces with fifteen CuZn3Cu9 cuboctahedra. There are three shorter (2.55 Å) andmore »
