Sodium uranyl acetate, NaUO/sub 2/(O/sub 2/CCH/sub 3/)a, is cubic with space group P2/sub 1/3 and alpha = 10.688 plus or minus 0.002 A. The positions of all atoms were deduced from precisely measured x-ray-diffraction intensities. In the collinear uranyl group U-O = 1.71 plus or minus 0.04 A. Normal to the uranyl axis are six secondary bonds from uranium to acetate oxygens with U-O = 2.49 plus or minus 0.02 A. Sodium is bonded to six acetate oxygens with Na-O = 2.37 plus or minus 0.04 A. The bond lengths within the acetate group are C-C == 1.52 plus or minus 0.05A, C--O=1.26 plus or minus 0.05A,and 1.28 plus or minus 0.04A, and 121 deg is found for the carboxyl bond angle. A revised bond length versus bond strength curve for U/sup VI/-O bonds is presented. (auth)
