Si Si Sb Cl
Si2SbCl crystallizes in the triclinic P1 space group. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 4-coordinate geometry to one Si(2), two equivalent Sb(1), and one Cl(1) atom. The Si(1)-Si(2) bond length is 2.24 Å. There is one shorter (2.12 Å) and one longer (2.72 Å) Si(1)-Sb(1) bond length. The Si(1)-Cl(1) bond length is 2.82 Å. In the second Si site, Si(2) is bonded in a distorted bent 120 degrees geometry to one Si(1), one Sb(1), and two equivalent Cl(1) atoms. The Si(2)-Sb(1) bond length is 2.69 Å. There is one shorter (1.55 Å) and one longer (2.03 Å) Si(2)-Cl(1) bond length. Sb(1) is bonded in a 4-coordinate geometry to one Si(2), two equivalent Si(1), and one Cl(1) atom. The Sb(1)-Cl(1) bond length is 2.71 Å. Cl(1) is bonded in a 3-coordinate geometry to one Si(1), two equivalent Si(2), and one Sb(1) atom.
