Materials Data on Y2CdCu2 by Materials Project
Y2Cu2Cd crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Y is bonded in a 6-coordinate geometry to six equivalent Cu and four equivalent Cd atoms. There are two shorter (2.88 Å) and four longer (2.93 Å) Y–Cu bond lengths. All Y–Cd bond lengths are 3.35 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Y, one Cu, and two equivalent Cd atoms. The Cu–Cu bond length is 2.51 Å. Both Cu–Cd bond lengths are 3.04 Å. Cd is bonded to eight equivalent Y and four equivalent Cu atoms to form a mixture of corner and face-sharing CdY8Cu4 cuboctahedra.
