When Friedel pairs are not averaged, the anomalous difference Patterson map calculated clearly showed the position of uranium atom. Using the anomalous data the final model has an R-factor of 0.231 and R-free of 0.264. THE ELECTRON DENSITY INDICATED ANISOROPIC MOTION OF THE URANIUM ATOM. THE POSITIONS OF URANYL OXYGENS WERE NOT CLEAR IN THE ELECTRON DENSITY MAPS. THE OXYGEN ATOMS WERE PLACED ACCORDING TO THE EXPECTED GEOMETRY AROUND THE URANIUM ATOM AND SEEM TO IMPROVE BOTH R-FACTORS.
