Materials Data on TaVCu by Materials Project
Abstract
TaVCu crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Ta is bonded in a 12-coordinate geometry to four equivalent Ta, six equivalent V, and six equivalent Cu atoms. There are two shorter (3.04 Å) and two longer (3.07 Å) Ta–Ta bond lengths. There are two shorter (2.93 Å) and four longer (2.95 Å) Ta–V bond lengths. There are four shorter (2.84 Å) and two longer (3.01 Å) Ta–Cu bond lengths. V is bonded to six equivalent Ta, two equivalent V, and four equivalent Cu atoms to form distorted VTa6V2Cu4 cuboctahedra that share corners with eight equivalent CuTa6V4Cu2 cuboctahedra, corners with ten equivalent VTa6V2Cu4 cuboctahedra, edges with six equivalent VTa6V2Cu4 cuboctahedra, faces with six equivalent VTa6V2Cu4 cuboctahedra, and faces with twelve equivalent CuTa6V4Cu2 cuboctahedra. Both V–V bond lengths are 2.40 Å. All V–Cu bond lengths are 2.51 Å. Cu is bonded to six equivalent Ta, four equivalent V, and two equivalent Cu atoms to form CuTa6V4Cu2 cuboctahedra that share corners with eight equivalent VTa6V2Cu4 cuboctahedra, corners with ten equivalent CuTa6V4Cu2 cuboctahedra, edges with six equivalent CuTa6V4Cu2 cuboctahedra, faces with six equivalent CuTa6V4Cu2 cuboctahedra, and faces with twelve equivalent VTa6V2Cu4 cuboctahedra. Both Cu–Cu bond lengths are 2.53 Å.
