Cr Cd Si Si
CrCdSi2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrCdSi2 cluster. Cr(1) is bonded in a 2-coordinate geometry to one Cd(1) and one Si(1) atom. The Cr(1)-Cd(1) bond length is 0.50 Å. The Cr(1)-Si(1) bond length is 0.50 Å. Cd(1) is bonded in a distorted single-bond geometry to one Cr(1), one Si(1), and one Si(2) atom. The Cd(1)-Si(1) bond length is 0.47 Å. The Cd(1)-Si(2) bond length is 1.07 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 2-coordinate geometry to one Cr(1), one Cd(1), and one Si(2) atom. The Si(1)-Si(2) bond length is 1.07 Å. In the second Si site, Si(2) is bonded in a 2-coordinate geometry to one Cd(1) and one Si(1) atom.
