LiAg(CO2)2 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Li1+ is bonded in a see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.07 Å. Ag1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ag–O bond distances ranging from 2.30–2.80 Å. There are two inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Ag1+, and one C3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Ag1+, and one C3+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Ag1+, and one C3+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, two equivalent Ag1+, and one C3+ atom.
