Pt5CdAs crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to two equivalent Cd(1) and two equivalent As(1) atoms. In the second Pt site, Pt(2) is bonded in a distorted square co-planar geometry to four equivalent Cd(1) atoms. Cd(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form a mixture of corner and face-sharing CdPt12 cuboctahedra. As(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms.
Pt5CdAs crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to two equivalent Cd(1) and two equivalent As(1) atoms. Both Pt(1)-Cd(1) bond lengths are 2.88 Å. Both Pt(1)-As(1) bond lengths are 2.52 Å. In the second Pt site, Pt(2) is bonded in a distorted square co-planar geometry to four equivalent Cd(1) atoms. All Pt(2)-Cd(1) bond lengths are 2.82 Å. Cd(1) is bonded to four equivalent Pt(2) and eight equivalent Pt(1) atoms to form a mixture of corner and face-sharing CdPt12 cuboctahedra. As(1) is bonded in a body-centered cubic geometry to eight equivalent Pt(1) atoms.
