Zn Re Si Si
ReZnSi2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ReZnSi2 clusters. Re(1) is bonded in a single-bond geometry to one Zn(1) atom. The Re(1)-Zn(1) bond length is 1.72 Å. Zn(1) is bonded in a 2-coordinate geometry to one Re(1) and one Si(1) atom. The Zn(1)-Si(1) bond length is 1.80 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 1-coordinate geometry to one Zn(1) and one Si(2) atom. The Si(1)-Si(2) bond length is 1.77 Å. In the second Si site, Si(2) is bonded in a distorted single-bond geometry to one Si(1) atom.
