Ag2CO3 crystallizes in the trigonal P31c space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. In the second C site, C(2) is bonded in a trigonal planar geometry to three equivalent O(3) atoms. In the third C site, C(3) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ag(1), one Ag(2), and one C(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ag(2), two equivalent Ag(1), and one C(3) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Ag(2), two equivalent Ag(1), and one C(2) atom.
