Abstract
Preston and Trotter1 have described a change of symmetry with temperature in the Laue photographs of basic beryllium acetate, Be4O(CH3COO)6. This change of symmetry, according to Preston and Trotter, is a reversible one and occurs between 30° and 50° C. At the higher temperature the crystal class possesses three-fold axes with parallel mirror-planes, whereas at the lower temperature only the three-fold axes are present. Preston and Trotter suggest that the increase in symmetry is due to the setting in of molecular vibration of the acetate groups.
