The compound described by RbAsO2 crystallizes in the orthorhombic Pbcm space group. Rb(1) is bonded in a 9-coordinate geometry to one As(1), four equivalent O(1), and four equivalent O(2) atoms. As(1) is bonded in a 3-coordinate geometry to one Rb(1), one O(2), and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to four equivalent Rb(1) and two equivalent As(1) atoms. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one As(1) atom. is represented by the CIF card [CIF]
