Rb2O is Hydrophilite-like structured and crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded to six equivalent Rb(1) atoms to form a mixture of corner and edge-sharing ORb6 octahedra. The corner-sharing octahedral tilt angles range from 51-56°.
