The single crystal structure of lead magnoniobate PbMg1/3Nb2/3O3 was determined at 20-degrees-C using data collected with an X-ray automatic four circle diffractometer. The average structure is cubic with space group Pm3m and exhibits important atomic shifts from the special positions of the cubic perovskite structure. The disordered local positions as well as the thermal parameters have been refined to final R index and weighted R(w) index of 0.0368 and 0.0378, respectively. Results are discussed in comparison with previous ones obtained by other techniques.
