Abstract
Abstract The electron diffraction study of tetramethoxymethane showed that in the gas phase the molecule has S 4 symmetry, flattened along the S 4 axis. Central and peripheral C-O bond lengths are different, consistent with considerations based on the anomeric effect. Comparison is made with ab initio calculations on methanediol. The geometrical parameters ( r g (1) structure) are: central C-O bond 1.395 A; peripheral C-O bond 1.422 A; C-H bond 1.11 A; O-C-O angle bisected by the S 4 . axis 114.7°; C-O-C angle 114.0°; O-C-H angle 111.9°; methoxy torsional angle 63.1°; methyl torsional angle 48.5°.
