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.
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. There are four shorter (2.85 Å) and four longer (3.03 Å) K(1)-O(1) bond lengths. C(1) is bonded in a trigonal planar geometry to one H(1) and two equivalent O(1) atoms. The C(1)-H(1) bond length is 1.11 Å. Both C(1)-O(1) bond lengths are 1.27 Å. 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.
