Cr Cr Cr Cr Cr Cd
Cr5Cd crystallizes in the trigonal R3m space group. There are three inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1), three equivalent Cr(2), three equivalent Cr(3), and one Cd(1) atom. Both Cr(1)-Cr(1) bond lengths are 1.50 Å. There are two shorter (2.79 Å) and one longer (3.22 Å) Cr(1)-Cr(2) bond length. There is one shorter (2.61 Å) and two longer (2.86 Å) Cr(1)-Cr(3) bond lengths. The Cr(1)-Cd(1) bond length is 2.14 Å. In the second Cr site, Cr(2) is bonded in a 16-coordinate geometry to four equivalent Cr(3), nine equivalent Cr(1), and three equivalent Cd(1) atoms. There is one shorter (2.79 Å) and three longer (2.99 Å) Cr(2)-Cr(3) bond lengths. All Cr(2)-Cd(1) bond lengths are 2.79 Å. In the third Cr site, Cr(3) is bonded in a 16-coordinate geometry to four equivalent Cr(2), nine equivalent Cr(1), and three equivalent Cd(1) atoms. All Cr(3)-Cd(1) bond lengths are 3.14 Å. Cd(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1), three equivalent Cr(2), and three equivalent Cr(3) atoms.
