Cr Cr Cd Cd
CdCr crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one CdCr cluster. Cr(1) is bonded in a 2-coordinate geometry to one Cr(1) and one Cd(1) atom. The Cr(1)-Cr(1) bond length is 2.12 Å. The Cr(1)-Cd(1) bond length is 1.59 Å. Cd(1) is bonded in a distorted single-bond geometry to one Cr(1) atom.
