The material structure described by RbCHO3 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. H(1) is bonded in a distorted linear geometry to one O(2) and one O(3) atom. There are three inequivalent O sites. In the first O site, O(3) is bonded in a single-bond geometry to two equivalent Rb(1) and one H(1) atom. In the second O site, O(1) is bonded in a single-bond geometry to four equivalent Rb(1) and one C(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one C(1), and one H(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
