Materials Data on DyGa2Cu3 by Materials Project
DyCu3Ga2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Dy is bonded in a 6-coordinate geometry to twelve equivalent Cu and six equivalent Ga atoms. All Dy–Cu bond lengths are 3.31 Å. All Dy–Ga bond lengths are 3.03 Å. Cu is bonded to four equivalent Dy, four equivalent Cu, and four equivalent Ga atoms to form a mixture of distorted edge, face, and corner-sharing CuDy4Ga4Cu4 cuboctahedra. All Cu–Cu bond lengths are 2.63 Å. All Cu–Ga bond lengths are 2.52 Å. Ga is bonded in a 9-coordinate geometry to three equivalent Dy and six equivalent Cu atoms.
