The crystal structure described by Li2ZnSi crystallizes in the trigonal P-3m1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 3-coordinate geometry to three equivalent Zn(1) and three equivalent Si(1) atoms. In the second Li site, Li(2) is bonded in a 2-coordinate geometry to one Zn(1) and four equivalent Si(1) atoms. Zn(1) is bonded in a 11-coordinate geometry to one Li(2), three equivalent Li(1), three equivalent Zn(1), and four equivalent Si(1) atoms. Si(1) is bonded in a 11-coordinate geometry to three equivalent Li(1), four equivalent Li(2), and four equivalent Zn(1) atoms. is represented by the CIF card [CIF]
