Sc Zn Si Si
ScZnSi2 is alpha Po structured and crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one ScZnSi2 cluster. Sc(1) is bonded in an L-shaped geometry to one Zn(1) and one Si(2) atom. The Sc(1)-Zn(1) bond length is 0.26 Å. The Sc(1)-Si(2) bond length is 0.30 Å. Zn(1) is bonded in an L-shaped geometry to one Sc(1) and one Si(1) atom. The Zn(1)-Si(1) bond length is 0.30 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in an L-shaped geometry to one Zn(1) and one Si(2) atom. The Si(1)-Si(2) bond length is 0.26 Å. In the second Si site, Si(2) is bonded in an L-shaped geometry to one Sc(1) and one Si(1) atom.
