The structure of the carboxyl group. II. The crystal structure of basic beryllium acetate

The crystal structure of basic beryllium acetate, Be4O(CH3COO)6, has been studied by Bragg and Morgan (1), who reported some spectrometric intensity measurements and showed the cubic unit of structure to have ao = 15.72 Å and to contain eight molecules, and by Morgan and Astbury (2), who showed the space group to be T4h. In neither study was the atomic arrangement determined. We have found an atomic arrangement which accounts satisfactorily for the data of these authors and for additional intensity data obtained photographically, and which provides information regarding the structure of the acetate group.
