The material described by KHCO2 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded to eight equivalent O(1) atoms to form a mixture of edge, face, and corner-sharing KO8 hexagonal bipyramids. C(1) is bonded in a trigonal planar geometry to one H(1) and two equivalent O(1) atoms. H(1) is bonded in a single-bond geometry to one C(1) atom. O(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one C(1) atom. is represented by the CIF card [CIF]
