BaAgZn2 crystallizes in the monoclinic Cm space group. Ba(1) is bonded in a 1-coordinate geometry to one Ag(1) and eight equivalent Zn(1) atoms. The Ba(1)-Ag(1) bond length is 2.46 Å. There are a spread of Ba(1)-Zn(1) bond distances ranging from 2.87-3.99 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ba(1) and four equivalent Zn(1) atoms. There are two shorter (2.87 Å) and two longer (3.16 Å) Ag(1)-Zn(1) bond lengths. Zn(1) is bonded in a 7-coordinate geometry to four equivalent Ba(1), two equivalent Ag(1), and one Zn(1) atom. The Zn(1)-Zn(1) bond length is 2.46 Å.
