Materials Data on Cu3Si by Materials Project
Abstract
Cu3Si is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Cu+1.33+ sites. In the first Cu+1.33+ site, Cu+1.33+ is bonded to eight Cu+1.33+ and four equivalent Si4- atoms to form distorted CuCu8Si4 cuboctahedra that share corners with twelve equivalent CuCu8Si4 cuboctahedra, edges with eight equivalent CuCu8Si4 cuboctahedra, edges with eight equivalent SiCu12 cuboctahedra, faces with four equivalent SiCu12 cuboctahedra, and faces with ten equivalent CuCu8Si4 cuboctahedra. There are four shorter (2.55 Å) and four longer (2.58 Å) Cu–Cu bond lengths. All Cu–Si bond lengths are 2.58 Å. In the second Cu+1.33+ site, Cu+1.33+ is bonded in a distorted square co-planar geometry to eight equivalent Cu+1.33+ and four equivalent Si4- atoms. All Cu–Si bond lengths are 2.55 Å. Si4- is bonded to twelve Cu+1.33+ atoms to form SiCu12 cuboctahedra that share corners with four equivalent SiCu12 cuboctahedra, edges with eight equivalent SiCu12 cuboctahedra, edges with sixteen equivalent CuCu8Si4 cuboctahedra, faces with four equivalent SiCu12 cuboctahedra, and faces with eight equivalent CuCu8Si4 cuboctahedra.
