KHCO3 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a single-bond geometry to four equivalent K(1) and one C(1) atom. In the second O site, O(1) is bonded in a single-bond geometry to two equivalent K(1) and one H(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one C(1), and one H(1) atom.
KHCO3 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. There is one shorter (2.91 Å) and one longer (2.95 Å) K(1)-O(1) bond length. There is one shorter (2.77 Å) and one longer (2.85 Å) K(1)-O(2) bond length. There are a spread of K(1)-O(3) bond distances ranging from 2.96-3.05 Å. C(1) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. The C(1)-O(2) bond length is 1.28 Å.
