Abstract
ErCu3Ga2 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Er is bonded in a distorted hexagonal planar geometry to ten Cu and eight equivalent Ga atoms. There are a spread of Er–Cu bond distances ranging from 2.94–3.31 Å. All Er–Ga bond lengths are 3.28 Å. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded to four equivalent Er, four equivalent Cu, and four equivalent Ga atoms to form distorted CuEr4Ga4Cu4 cuboctahedra that share corners with eight equivalent CuEr4Ga4Cu4 cuboctahedra, corners with eight equivalent GaEr4Ga2Cu6 cuboctahedra, edges with two equivalent CuEr4Ga4Cu4 cuboctahedra, edges with eight equivalent GaEr4Ga2Cu6 cuboctahedra, faces with two equivalent CuEr4Ga4Cu4 cuboctahedra, and faces with eight equivalent GaEr4Ga2Cu6 cuboctahedra. All Cu–Cu bond lengths are 2.52 Å. All Cu–Ga bond lengths are 2.55 Å. In the second Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Er, two equivalent Cu, and four equivalent Ga atoms. All Cu–Ga bond lengths are 2.55 Å. Ga is bonded to four equivalent Er, six Cu, and two equivalent Ga atoms to form distorted GaEr4Ga2Cu6 cuboctahedra that share corners with four equivalent CuEr4Ga4Cu4 cuboctahedra, corners with twelve equivalent GaEr4Ga2Cu6 cuboctahedra, edges with four equivalentmore »
