Abstract The colourless compound RbNaO has been prepared as described earlier [1 ], but single crystals were not yet available at that time. N ow its crystal structure was determined by X-ray diffraction techniques. The very hygroscopic RbNaO crystallizes in the tetragonal space group P4/nmm (Z = 2) with the cell parameters a - 406.8(1), c = 649.4(1) pm. The structure was solved from 1031 counter reflections (375 symmetry independent reflections) by using differential Fourier syntheses. Refining gives a least squares residue o f 0.086. The structure forms an am/-PbFCl-type geom etry with c-centered squares of sodium interspersed by antiparallel ordered pairs of R b-O
