KC2H3O3 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one KC2H3O3 sheet oriented in the (0, 0, 1) direction. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.73–3.09 Å. There are two inequivalent C1+ sites. In the first C1+ site, C1+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.25–1.41 Å. In the second C1+ site, C1+ is bonded in a tetrahedral geometry to three H1+ and one O2- atom. All C–H bond lengths are 1.10 Å. The C–O bond length is 1.44 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C1+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent K1+ and two C1+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one C1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four equivalent K1+ and one C1+ atom.
