The structure of rubidium molybdyl arsenate consists of AsO4 tetrahedra and MoO6 octahedra sharing corners to form a three-dimensional framework containing large tunnels, parallel to [110], where the Rb+ ions are located. RbMoO2AsO4 is isostructural with the phosphate KMoO2PO4. They both crystallize in the orthorhombic space group Fddd.
