LiAgZn2 is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LiAgZn2 clusters. Li(1) is bonded in an L-shaped geometry to two equivalent Zn(1) atoms. Both Li(1)-Zn(1) bond lengths are 0.22 Å. Ag(1) is bonded in an L-shaped geometry to two equivalent Zn(1) atoms. Both Ag(1)-Zn(1) bond lengths are 0.22 Å. Zn(1) is bonded in an L-shaped geometry to one Li(1) and one Ag(1) atom.
