The material structure described by Ag2CO3 crystallizes in the hexagonal P-6 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), and two equivalent O(3) atoms. In the second Ag site, Ag(2) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted edge-sharing AgO5 trigonal bipyramids. 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(2) atoms. In the third C site, C(3) is bonded in a trigonal planar geometry to three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ag(1), two equivalent Ag(2), and one C(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ag(1), two equivalent Ag(2), and one C(2) 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(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
