The material described by KAgCO3 crystallizes in the orthorhombic Ibca space group. K(1) is bonded in a 9-coordinate geometry to four equivalent O(2) and five equivalent O(1) atoms. Ag(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to five equivalent K(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent Ag(1), and one C(1) atom. is represented by the CIF file [CIF]
