NaAg(CO2)2 crystallizes in the monoclinic P2_1 space group. Na(1) is bonded to one O(3), two equivalent O(4), and three equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing NaO6 octahedra. The corner-sharing octahedral tilt angles range from 65-82°. Ag(1) is bonded in a 5-coordinate geometry to one O(3), one O(4), and three equivalent O(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Na(1) and one C(2) atom to form distorted corner-sharing ONa3C tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ag(1) and one C(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Na(1), one Ag(1), and one C(1) atom. In the fourth O site, O(4) is bonded in a 1-coordinate geometry to two equivalent Na(1), one Ag(1), and one C(2) atom.
